Hire the Best Game Developers
in Japan

Hi, I'm Yohan—a former programmer at two Japanese studios, now a full-time indie developer and consultant. I build fun, polished games and prototypes fast, then help you take them all the way to launch. What I can do for you End-to-End Game Development PC, console, Android, iOS Unity (C#), Unreal Engine 5 (C++/Blueprints) & Godot (C#/GDScript) Optimised builds, store-ready packages Multiplayer & Live Ops Photon Fusion / Mirror / PlayFab Unreal Networking & EOS Matchmaking, leaderboards, live events Next-Gen AI-Assisted Development (Optional) Fast Concept Validation – I use AI to quickly prototype and pressure-test ideas, so we know a mechanic is fun before investing in production code. Efficient Feature Scaling – Once I've built a rock-solid architecture, I offload routine feature work to AI to accelerate delivery while keeping review tight. No Blind Automation – I never hand complex debugging or core architecture to AI. Keeping humans in control of the foundations avoids the performance hits and technical debt that AI-generated code often introduces. Game Design & Documentation Original concepts, monetisation hooks GDDs, technical specs, task breakdowns QA & Play-Testing In-depth bug hunts, balance reviews Actionable reports with clear fixes Why clients hire me Pro studio background – shipped hyper-casual mobile titles, VR experiences, and console/PC projects in Japan. Full-stack mindset – code, design, art pipelines, build automation, Web3/NFT integration. Speed with quality – clear milestones, frequent builds, no surprises. Creative partner – I don't just execute; I suggest fresh ideas and better workflows. Let's talk.

I help indie developers and small studios turn game ideas into playable prototypes quickly. Making games since 2016, I've shipped titles on Steam and Google Play Store, and won a gold award at the HAL Tokyo Game Jam. I'm currently studying game programming at HAL Tokyo, one of Japan's top game development schools. What I'm good at: - Building prototypes and game mechanics quickly in Unity - Taking a concept from idea to playable in days, not weeks If you have a game idea that needs to become real, feel free to contact me.

Make every hour count. For game dev jobs - also provide discounts. Member of "Visionary Impact" team on Steam (game: Cycle of Struggle: Ardengrad) Founder of non-profit community-driven organization: "Shade of Singularity" (SoG): We strive to provide best solutions on the market, so you won't need to trade off performance and security for convenience and nice development experience. It's all about people after all. I also offer up to 25% discount for game development jobs ^-^ - 20-25% for free games or with one-time payment model. - 15-25% for games with ads-only or mild monetization. - 10% for games with high reliance on micro-transactions. One-time payment model is a lot riskier. That's why I support it more. But personally - I like to experiment! And I like it a lot! I have 5 years of commercial experience with C#, Unity and Java, and over 7 of non-commercial. My field of expertise is Software Development, of any kind, with high performance in mind. Performance is enforced not by rules, but rather by creation of intuitive API, whenever possible. And optimizations work around this intuitive development workflow. Very experienced in planning-out systems from a ground up for extremely large applications. With my team we develop games and software for players and streamers; we setup servers for community events, proxy servers and servers for SaaS for our ideas. We also develop mods for games and collaborate on smaller things all the time. Besides that, for work I wrote applications for all devices: Android, Linux, Windows, thanks to C#, Java and Node.js (deployment on Versel). Video players for TV & Internet provider company, and participated in smaller projects. Open for work on C++ as well. Other languages, depending on a circumstances, will require some preparation. Quick learner, especially with explicit practice. If you need any help with planning - hit me up! If I have a free minute - it will be my pleasure to think through some solutions and problems your project might encounter, it's very fun)
