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.
