About

I'm a Unity developer with six years in gameplay programming, cross-platform development, and simulation technology. My work spans Unity3D, Unreal Engine, and C++ — with a habit of chasing performance headroom and clean architecture wherever I land.

Most recently that's meant building an immersive flight-training device and AR/VR technical-training tools for MRO work, including a Nakama-backed multiplayer layer handling 2,000+ concurrent entities. Earlier chapters include shipping mobile titles at Bombay Play, gameplay systems on Zynga's FarmVille 3, and a mobility-assistance system for paralyzed patients at BeAble Health.

I'm drawn to technology with a purpose beyond entertainment — healthcare, defence, and education in particular — without losing sight of what makes a build actually feel good to play.
