Building & shipping software since age 13

From bedroom game dev
to production systems at scale

I started building games at 13 years old with Unity 3D — not as a school project, but because I wanted to make my own games. I taught myself C#, published ~7 games on the App Store and Play Store, and earned my first software revenue as a teenager.

That same drive to build and ship never stopped. Today I architect production backend and frontend systems for international clients. I'm deeply fluent with AI-assisted development and use tools like Claude Code and Codex daily to accelerate everything I build.
