About me

Profile Image

My background spans 5+ years of professional game development, from commercially released mobile and PC titles to projects delivered directly for clients.

I work on gameplay systems, progression and economies, backend integration, debugging, optimization, and release preparation. I can join an existing codebase, take ownership of unfinished systems, or develop a project from prototype through delivery.

Unity and C# are my primary stack, but I adapt to the project. My work has also included Godot, browser-based games, and Firebase across Android, iOS, and Steam.

Whether I’m part of a development team or working directly with a client, I take responsibility for implementation, testing, technical decisions, and delivery without needing constant oversight.
