Using modern AI coding tools feels like jumping into the cockpit of a BattleMech. My co-worker used this analogy recently and I love it. It perfectly sums up the feeling of vibe coding for me. I can move faster, jump higher and it feels like a there is a whole new world of possibilities available to me. This is true for me as someone who no longer writes code every day, but many experienced software engineers don’t feel this way and I get it. They’ve been running around on foot and learned to be very effective without it. Jumping into the cockpit of something entirely new is jarring. The BattleMech can feel clunky, burdensome and they basically have to relearn all their instincts around movement and orientation (it can also sometimes shoot itself in the foot!). On top of this, many non-technical folks have also jumped into the BattleMech. They are running off in all these strange directions because they don’t know what to use it for. They are copying things, building things that suck and filling social media feeds with their creations. Many software engineers feel the same way as artists did a few years ago because pretty much anyone can create software now. The good news is that domain knowledge and software development instincts are still essential. The BattleMech can be incredible if you know exactly where you want it to go, but it’s also happy to lead you straight off a cliff.
Progress Quest is generally considered the original idle game. It came out in 2002 as a parody of EverQuest and the emerging MMORPG boom. “Playing” it consists of creating a character, clicking “Sold!”, and then watching progress bars fill forever. There’s no interaction, no real gameplay, just waiting. At first glance, it feels like a gimmick — a joke game built to poke fun at the MMO trend. But what’s surprising is that its creator, Eric Fredricksen, built a whole RPG simulation underneath the progress bars. There are 270+ monsters, procedurally named equipment, multiple storylines, intentionally weighted stats, real loot tables, and a surprisingly complex progression system. On top of that, there’s even an authentication system for competitive multiplayer leaderboards that are somehow still around today. I love Progress Quest because of its absurdity, but also because it’s such a good example of something being far better than it needed to be. The amount of effort and attention to detail in this game makes me smile. Exponential Progression At the heart of Progress Quest is a single formula that controls level progression. The time it takes to complete level N is: (20 + 1.15^N) * 60 seconds. That means early levels take minutes (a few hours to get to level 10), while later ones take years (many years to get to level 100). There is also additional time outside of leveling for the player to go to market, buy/sell things, and head back to the “killing fields”. There are still thousands of players active across the remaining multiplayer realms, and pretty much everyone above level 95 has had the game running for over a decade. That doesn’t even count single-player characters. Races and Classes The race and class systems are hilariously absurd, but they don’t affect gameplay at all. The player races are: Half Orc, Half Man, Half Halfling, Double Hobbit, Hob-Hobbit, Low Elf, Dung Elf, Talking Pony, Gyrognome, Lesser Dwarf, Crested Dwarf, Eel Man, Panda Man, Trans-Kobold, Enchanted Motorcycle, Will o’ the Wisp, Battle-Finch, Double Wookiee, Skraeling, Demicanadian, and Land Squid. And the classes are: Ur-Paladin, Voodoo Princess, Robot Monk, Mu-Fu Monk, Mage Illusioner, Shiv-Knight, Inner Mason, Fighter/Organist, Puma Burgular, Runeloremaster, Hunter Strangler, Battle-Felon, Tickle-Mimic, Slow Poisoner, Bastard Lunatic, Jungle Clown, Birdrider, and Vermineer. Hilarious Monster Types There are over 270 hand-crafted monsters, and every one of them has a thematic loot drop. The Giant series imagines what giants would be if they were made of basically anything: Humidity Giant (drops “drops”) Beef Giant (drops “steak”) Rice Giant (drops “grain”) Porcelain Giant (drops “fixture”) Mini Giant (drops “pompadour”) The Golem series follows the same logic: Beer Golem (drops “foam”) Oxygen Golem (drops “platelet”) Cardboard Golem (drops “recycling”) The Scout hierarchy is great: Cub Scout (drops “neckerchief”) Girl Scout (drops “cookie”) Boy Scout (drops “merit badge”) Eagle Scout (drops “merit badge”) The Elemental series is an entirely new take on Elementals: Bacon Elemental (drops “bit”) Cheese Elemental (drops “curd”) Hair Elemental (drops “follicle”) Porn Elemental (drops “lube”) When the game picks a monster to fight, it level-matches against your character and then applies modifier prefixes based on the gap. That adds more flavor to the monster names. Procedural Equipment When you get new gear, the game doesn’t just pull from a list. It runs a little algorithm: Pick a base item matched to your level from a list like Stick → Shiv → Longsword → Halberd Calculate the quality gap between the item’s base level and your level “Spend” that gap across up to two modifier adjectives, each with a point value Whatever is left becomes a numeric +N prefix So a level 40 character might find a +13 Custom Holy Mithril Mail — a level 19 Mithril Mail base, with Custom (+3) and Holy (+5), leaving +13 unspent. The modifier tables are split into good and bad. If the gap is negative — meaning the item is actually better than you — the game pulls from the bad list instead: Rusty, Dull, Bent, Plastic, Nerf (-7), Rubber (-6). There’s also a whole list of spells with names like “Holy Batpole,” “Grognor’s Big Day Off”, and “Roger’s Grand Illusion” that will make their way into your spellbook and increase in level with roman numerals. The Main Game Loop Surprisingly, the game has a real game loop. It works like this: Kill monster task — The game generates a monster with a duration based on your level. When the timer finishes: Loot is added to your inventory, either a specific drop or generic loot XP is gained, which can trigger a level-up Quest and plot bars advance Check encumbrance — After a kill, if encumberance is at or above your limit, you go to market instead of fighting: The game will say “heading to market to sell loot” Then the game sells items one at a time, removing the top item in inventory and adding gold Items with “of” in the name sell for much more This continues until only gold remains Buy or head out — After selling, or if you weren’t encumbered in the first place: If the player’s gold is high enough to buy better gear, the game says “Negotiating purchase of better equipment” and the game upgrades a random equipment slot Otherwise the game will say “Heading to the killing fields” Next kill — After heading out, the game generates another monster and the cycle repeats Stat Progression When you gain a stat point, the game uses a weighted system biased toward your highest stat. Half the time, the gain is completely random. The other half uses quadratic weighting, where each stat’s chance is proportional to its value squared. That creates a snowball effect where your best stat keeps getting better, which feels authentic to how RPG builds tend to work. The only real strategy to playing Progress Quest is trying to roll high STR at character creation. Having higher STR gives you higher max encumberance which affects how often you need to go to market. The thing is, the market trips are such a small fraction of actual game time that this only about a 5% difference in how fast your character will level up. In Conclusion This is probably more than anyone wanted to know about Progress Quest. It’s an absurd, charming little game, and I hope it somehow keeps living forever. If you want to play the “multiplayer” Windows version, you can download it here. I also wanted to play on my Mac, so I vibe-coded an Swift version that runs on modern Mac hardware. See you on the killing fields!
I made a retro-inspired dock to charge my Playdate out of a Raspberry Pi case. The case is a miniature version of the Super Famicom and I love how it makes the Playdate look like a little game cartridge when it’s charging. Making one yourself is pretty straight-forward, you’ll just need the following components: Retroflag SUPERPi case A compact right-angle USB-C cable, like this one The 3D printed insert I designed First, print the two halves that make up the 3D printed insert and attach them with super glue. Make sure to align the cutouts on each side and then clamp the two pieces in place while the glue dries. Then take the Retroflag case apart and unscrew the main board. You’ll have to cut some wires and remove the front-facing USB ports. Make sure to leave the rear-facing USB-C port in place as we’ll reuse this to power the Playdate. Then, using a Dremel, cut a rough 86 by 21 mm rectangular hole in the top of the case. It doesn’t have to be clean as it will get covered up by the 3D printed insert. You will also need to remove some of the internal support structure inside the case using pliers or flush cutters to make space for the insert and wires. After it has dried, insert the 3D printed piece through the hole and hot glue the right-angle USB-C cable into place. Lastly, splice the USB-C cable to the red and black wires coming off the rear-facing USB port on the case. The red (or pink) USB-C cable wire should be spliced to the red wire on the USBC-C port. The two black wires should also be spliced together. That’s it! At some point I’d like to make it into a functional USB hub and add an internal LED.
A few years ago, I built a Wi-Fi-controlled Nerf turret, but I never got around to creating a proper build guide for it. When I finally sat down to write one, I realized just how many things I would do differently. That realization quickly snowballed into a full redesign—and the result is a vastly improved version of the SwarmTurret. This new version is not only more powerful and precise, but it’s also easier build. Here are some of the major upgrades: Simplified Assembly: I reused the shell of an existing plastic blaster, which significantly cuts down on 3D printing and makes putting it together much easier. Improved Stability: A new belt-driven Y-axis adds smoother motion and includes an adjustable tension system. Enhanced Accuracy: The camera has been repositioned for better aiming precision. Direct X-Axis Drive: I replaced the original gear system with direct motor control for more responsive movement. Performance Boost: Upgraded from Raspberry Pi 4 to Pi 5 for faster web app performance. Integrated Power Supply: Now features a built-in power supply with an on/off switch—no more fumbling with cables. Web App Enhancements: The control interface is more intuitive and responsive. I’ve published the complete build guide, along with the updated code and 3D printable parts.
3D Printing has allowed me to be creative in ways I never thought possible. It has allowed me to create products that provide real value, products that didn’t exist before I designed them. On top of that, it’s satisfied my desire to ship products, even if the end-user is just me. Another great thing is how quickly 3D printing provides value. If I see a problem, I can design and print a solution that works in just a few hours. Even if I’m the only one who benefits, that’s enough. But sharing these creations takes the experience even further. When I see others use or improve on something I’ve made, it makes the process feel so much more worthwhile. It gives me the same feeling of fulfillment when I ship software products at work. Before mass-market 3D printing, creators would need to navigate the complexity and high costs of mass-production methods (like injection molding) even to get a limited run of a niche product produced. With 3D printing, they can transfer the cost of production to others. Millions of people have access to good 3D printers now (at home, work, school, libraries, maker spaces), which means almost anyone can replicate a design. Having a universal format for sharing 3D designs dramatically lowers the effort that goes into sharing them. Creators can share their design as an STL file, which describes the surface geometry of their 3D object as thousands of little triangles. This “standard currency” of the 3D printing world is often all that is required to precisely replicate a design. This dramatically lowers the effort that goes into sharing printable designs. The widespread availability of 3D printers and the universal format for sharing 3D designs has allowed 3D-printed products to not only exist but thrive in maker communities. This is the magic of 3D printing: it empowers individuals to solve their own problems by designing solutions while enabling others to reproduce those designs at minimal cost and effort.

Many people say that to find a software engineering job in Japan, you need to be here first. The most common ways into Japan without a job are to become a student, arrive on a Working Holiday visa, or use the J-Find visa — all of which mean spending a lot of money just to show up and still not be sure it will work out. When I was a university student in India, I knew very well that getting hired as a junior software engineer in Japan while still overseas would be difficult. It makes sense, as companies here hire on trust, and trust is hard to build at a distance. But Japan is also a country staring down a shortage of hundreds of thousands of IT workers by 2030, with foreign workers already at a record 2.6 million and still climbing. The door is harder to get through, but there’s a whole line of people worldwide standing in front of it, and the country actually needs them to come in. Now I’m a tech lead at a Japanese startup, where we help people find and buy abandoned homes (空き家, akiya), which made up a record nine million properties in the government’s 2023 survey. I’ve lived in Japan for just over a year. I know there are a lot of people out there chasing the same Japan dream, working hard for it just like I was a few years ago, so I hope they can get a few ideas from someone who has already done it. How I got hired as a junior software engineer from overseas What I’ve learned working as a software engineer in Japan How to get a junior software engineering job in Japan Conclusion How I got hired as a junior software engineer from overseas I came to Japan despite many hurdles. Let me lay out everything that happened, and everything I did, to close the gap between me and what I wanted My starting point I started a four-year computer science degree in 2020, and it was the first time I was studying something I actually cared about. My grades sat around 8.9 out of 10 each semester and it barely felt like work. That taught me something I still believe, which is that the hard part is never the studying, it is finding the things worth studying. For me, one of those things was Japan. I’d trained in karate back in India up to green belt, and that pulled me towards the culture. I soon found I also loved the food, the nature, and the level of hospitality. So I set a goal: get my first job in Japan within three years. I also knew the usual route to Japan my classmates took—the mass campus placements, with hundreds hired in one batch—wasn’t for me. I didn’t think I was above it, but I could easily see myself disappearing into the crowd. Instead, I went looking for another way in. Finding a door to Japan What I needed was a connection, a thread that could somehow link me from South Asia to Japan. I started finding LinkedIn groups that let you work as an intern at Japanese startups. These startups were usually run by big players in Japan, often international residents, who could be the CEO or founder of many smaller companies. These are the English-friendly ones I joined back in the day: Internship opportunities in Japan Internship Japan Business in Japan They’re all pretty slow now, but in 2021 they were bustling, almost crazy with activity. The first two are internship-focused ones: students post their skills and resume, and managers share openings you can apply to directly. The Business in Japan group is different, and more of an entrepreneur crowd, but I joined it because those are exactly the people who can hire you. The one that worked best for me was Internship opportunities in Japan, because that’s where I found my first connection. I strongly recommend that group to anyone wanting an internship. Whether they start paying you depends on the company, what stage they’re at, and how much trust you’ve built with them. Preparing for a Japanese internship When I joined the groups, my resume was super odd, and I couldn’t have gotten a job or an internship with it. Still, I joined and added my Japanese-style self introduction in English. After a few days, one of the group admins messaged me about whether I wanted an internship, and then asked for my resume. It was really bad, but I sent it anyway, and we came to the mutual conclusion that I could come back later with a better skillset. Later that year I started building my skillset on my own. Honestly, you have to be a few steps ahead of your university, since they won’t teach you exactly what you will end up building at a company. At that time most people I knew went the Data Structures and Algorithms (DSA) route, which means you grind a lot of DSA, crack the interview, and figure out real building later. I went a different way. I started with learning how design actually works, and it turned out to be less difficult than it was time-consuming: you have to build a real taste for what goes where and what pairs with what. You can’t slap a Roboto font on an established news site. That went into my portfolio, which I started early and have rebuilt many times. Alongside it I shipped small personal projects to make life easier for me and the people around me, because even a silly MBTI test you play with friends is a real product if you know what you’re building. I also joined online hackathons (my mailbox was always full of stickers from them). My first real shot at a job in Japan About eight months later I went back to the admin of the internship group with these new experiences, and this time I got the chance to work with a few people from Japan Travel. The CEO of Japan Travel, Terrie Lloyd, is also the founder of Daijob, one of the country’s most well-known job platforms. Lloyd’s a Kiwi entrepreneur who landed in Japan back in 1983 on a Working Holiday visa, at 24 years old, with no degree and no Japanese, and still went on to build company after company. I was getting my chance from someone whose own story was proof that an “impossible” path was possible. We were building an idea called O2O Stays, basically a marketplace for accommodation nights. Hosts could sell nights in bulk upfront at a discount, and buyers could use them, resell them, or trade them—kind of like the short-term rentals you already know, but more flexible. I took it even though it was unpaid, for a simple reason: I had never worked at a real technical firm, and this looked like no risk and high reward. You can teach yourself to build websites, but the things that actually matter—like system design, Core Web Vitals, and the real-world problems you encounter—you only learn once actual people start using what you built. That was worth more to me than getting paid right away. My task was to build an informational website. This honestly felt huge to me back then. It was also my first real deadline and I underestimated it. The timeline slipped more than I wanted, but I was lucky to be on a team with genuinely good people, so we figured it out and shipped it. At the end I got my first letter of recommendation from my Internship, and that one letter opened the door to multiple internships after it. Building while learning A lot of that early internship experience was unpaid, and I was fine with that, because when you have no track record, even the experience itself is worth a lot. But then things started to change. In my third year at university, one of the best places I worked with was MarkoKnow, a Delhi-based startup. That’s where I built my first real application and a few admin pages, and gained a lot of firsthand knowledge. By the end I felt like I could build anything (though that was probably just the adrenaline rush). Those experiences made me want to learn more, about whatever I could do with just me and my laptop. I put a lot of time into researching Web3 and even built a project out of it that got published on IEEE with one of my university classmates. I dabbled in VR, AR, and IoT too, but the one that mattered most in the long run was machine learning, which would end up helping me a lot further down the line. I also made sure to stay in touch with people I’d met during my internships. I sent them updates on what I was building, shared my portfolio and resume each time they got better, took genuine interest in the work their companies were doing and where tech could push it further, and stayed visible by commenting on posts and checking in. Turning a connection into a job at AKIYA2.0 By August 2023 I was 20 years old, my final year of university was approaching, and my main motivation was to get a job fast. The usual path would have been an internship that converts into a pre-placement offer, and landing one in my home country is a real achievement. But the thing was, I still wanted to be in Japan. I went back to the connection I’d kept warm and asked for a new opportunity. That follow-through was what kept the door open, and this time it opened onto a great one: Terrie was on the verge of co-founding another company. It had something to do with abandoned homes, and they were offering a paid part-time job. My first task was to understand the abandoned home market and build a small scraper for a single municipality, using Tesseract OCR to read through documents, since AI still had a really bad name back then. It wasn’t pretty: on that early setup, our scraping accuracy sat around 60-70%, and validation was lower still. Later we migrated the whole thing to Gemini, which pushed scraping close to 99.5% and cut our costs by around 96%. I loved the work, and almost without noticing I drifted into much more than just software engineering. Being at a startup, I was soon hiring interns and part-timers, leading projects, and building new services and tools on my own so that nobody had to manage the extra pieces I was adding. By the time they brought me on as a full-time software engineer in March 2024, the title just formalized what I was already doing. Finally, Japan I’d just graduated that spring, and I wanted to spend a year living with my family, since I’d spent most of my life in other cities at boarding school, hostels, and university. The job with AKIYA2.0 allowed international remote work, so I had the option to stay home with my family for a year, and that was something I didn’t want to skip. Then, in April 2025, I finally moved to Japan. The move itself was surprisingly simple, because my company handled most of the paperwork. I just sent over some documents and they filed for my Certificate of Eligibility (COE). It took exactly two months, and it arrived on my birthday, while I happened to be in Singapore. I had to return to India to get the visa process started. It went smoothly and I got a three-year Engineer/Specialist in Humanities/International Services visa. What I’ve learned working as a software engineer in Japan In my three years at AKIYA2.0 so far, I’ve built three websites: https://www.akiya2.com/ https://www.singchamjapan.org/ https://www.hinokistays.com/ I also built an AI scraper covering all 47 prefectures in Japan, and became genuinely good at SEO, GEO, and system design, while managing a bunch of interns and part-time engineers. And I’m still chasing more—I want to be great at all of it. ^The mindset that got me here is simple: don’t think only about survival. Think about making your presence so bright that it becomes hard to ignore you. That mindset still matters after you arrive, because moving to Japan doesn’t make everyday problems disappear. You still have to build a life here, and how difficult that feels depends a lot on who you are and what you’re used to. For a lot of people, that adjustment is the hardest part, sometimes even harder than landing the job in the first place. The daily friction adds up in ways you don’t expect. You might have dietary restrictions, feel suffocated on a rush-hour train, spend the entire weekend recovering from the working week, or simply feel lonely. For me, the adjustment wasn’t especially difficult. I had always wanted to live independently, and after years in boarding school and hostels, I was used to being away from home. What Japan unexpectedly gave me was a real sense of freedom, because I could work during the week and travel on the weekends. That has honestly been the best part of my experience, particularly the peaceful countryside, beautiful nature, and countless shrines I’ve come across along the way. If I had the chance to start again, I would get properly good at Japanese before moving. Living here without it is possible, but knowing the language opens up far more of the country: events, friendships, relationships, jobs, and the connections that might eventually lead to a startup opportunity or even a course at a Japanese university. When you’re already living in Japan, it feels like a shame to miss so much of what is happening around you. How to get a junior software engineering job in Japan Where to find junior software engineering jobs in Japan from overseas In my experience there are two kinds of people who don’t make it: the ones who never get an opportunity, and the ones who get one but give up. The ones not getting opportunities are usually just not searching in the right places, or not building a network. How do you find opportunities? You look for them online and in communities. TokyoDev lists junior developer jobs, and is one of the best examples of how much networking matters in this career, and LinkedIn is a great tool too, if you learn how to use it. There are CEOs, CTOs, and COOs from startups and big firms sitting right there on LinkedIn and X. So what’s stopping you from a cold email? Build a portfolio that gets you noticed But a tool only gets you in front of people; after that you have to impress them. As a software engineer, the only real way to impress someone is by building something for them. And to earn that chance, you first have to get good at the basics. ^About 95% of what companies build isn’t niche or original. It’s the same kind of product that already exists across many businesses, and often in open source too. Only a small slice, maybe 5%, is truly novel. Don’t run for that 5% yet, not while you’re starting out. Get genuinely good at the 95% first, because that’s what almost every real job actually involves. After all, working in Japan isn’t niche either. The competition is huge, and being a real professional is what sets you apart. Being a professional shows in the specifics. If you’re a frontend engineer, don’t tell me you know React or Vue, middle schoolers know them by now. Show me the components you built that made your own life easier, your page load times, your Core Web Vitals, and how your SEO holds up. If you’re a backend engineer, talk about the choices you’d make for a given product, the alternatives you actually know, how you cut costs, and how you fill the gap between a developer who just writes code and an engineer who takes responsibility. That attitude is exactly what I look for when I interview interns, part-timers, or engineers. Learn what software engineering skills are in demand in Japan Another tip is to study your market and see what’s booming right now. AI is the obvious hot topic, and Japan is pouring serious money into it lately. The government has committed over 10 trillion yen (around 65 billion US dollars) in public support for AI and semiconductors through 2030, and for the coming fiscal year it nearly quadrupled its chip and AI budget to about 1.23 trillion yen (7.9 billion dollars). AI startups often get founded by certain kinds of people—Japanese citizens returning from abroad, PhD holders from Todai or Waseda, and sometimes international residents as well. Sakana AI is a good example, founded by David Ha, Llion Jones, and Ren Ito. Some of these companies even have English-speaking roles. Conclusion So target thriving sectors like AI, but keep a backup plan. And seriously, start studying Japanese, because looking at the market now it matters more and more. However, I moved to Japan in April 2025 with no Japanese at all, so there’s always a way. Don’t lose hope. If you have the right mindset, can find the places where opportunities live, and are as persistent as you possibly can be, then with time you’ll look up and realize you already have everything you were chasing. Honestly, if I can do it, I’m sure anyone reading this can too, so keep trying.
