I am a Unity Game Developer with 7 years of professional experience, specializing in mobile games, multiplayer systems, AR experiences, and 2D/3D games that go beyond the editor and into the hands of real players. I use AI-assisted workflows to speed up prototyping, boilerplate code, and testing — but every architecture decision, performance optimization, and final build is planned and verified by me, not automated blindly. I have personally delivered numerous games across Steam, Google Play Store, and WebGL, end-to-end, from initial architecture to final store submission. I have built games from scratch, stepped into half-finished projects other developers (and AI tools) left incomplete or broken, and shipped live updates without breaking what was already working. My expertise covers Photon Fusion, Unity Netcode, Mirror, AR Foundation, Firebase, PlayFab, URP, HDRP, and the full Unity toolchain, combined with modern AI tooling for faster iteration. I plan architecture before writing a single line of code, test under real player conditions, and communicate proactively, no surprises at the deadline. STRENGTHS: ✔ 7+ years of dedicated Unity development across mobile, multiplayer, AR, 2D and 3D ✔ Numerous published games on Steam and Google Play Store, not demos, real products with real players ✔ AI-accelerated development: faster iteration and prototyping without sacrificing code quality ✔ Full-cycle delivery, concept, architecture, development, publishing, and post-launch support ✔ Multiplayer specialist, systems built and debugged under real player conditions, not just local testing ✔ Project rescue expert, including fixing half-finished AI-generated or abandoned Unity projects ✔ Performance-first approach, optimized for real-world devices, not just high-end test machines ✔ Honest scoping, if something isn't feasible in your timeline or budget, I tell you before starting, not at delivery

I will create a game or gameplay system that you have in mind and make the process as iterative as possible so you always get what you asked for.  I have experience with clients hiring me after other freelancers failed to deliver what they needed or believed it was not possible to implement, and I solved the problem. What tasks can I accomplish: - Building a Finite State Machine for AI or various characters in a game - Implementing Multiplayer - Implementing gameplay mechanics - Implementing procedural shaders with Shader Graph - Integrating various assets into a game - Refactoring code - Prototyping a game - Developing various placeholder or simple assets for a game I have worked as a game dev and 3D modeler for 5+ years as of now. I helped clients to bring various tasks they needed, including building an addon that uses an isometric system to stack objects on each other without z-index issues. Using my knowledge of procedural materials, I created a procedural island for a calendar application, made a rocket launcher simulator for presentation for military organizations, developed card-based combat for a visual novel game, and so on.   My unique value is in having both game development and programming skills and also experience with making 3D models. I have good orientation in 3D space and have skills in building procedural materials using a Shader Graph and also using procedural textures for various other purposes, for example, generating specific 3D terrains or objects.  If you're ready to bring your game idea to life, message me to discuss your project timeline and scope.
