Full-stack developer

Turning ideas into playable experiences with clean code, thoughtful design, and systems that hold up beyond the first build.

I build games, AR tools, mobile apps, and backend systems with the same goal: make the experience feel alive, readable, and sturdy enough for real players.

About

Game developer by heart, systems builder by practice.

My work sits between playful interaction and dependable engineering: Unity games, AR mobile experiences, PWA tools, APIs, and the leadership needed to guide teams from rough prototype to playable release.

Prototype the fantasy early so the core interaction has a pulse.

Build systems that support content, iteration, and live feedback.

Keep the code clear enough for future collaborators and future me.
