What I'm looking for

I am seeking a role where I can lead gameplay/system development on PC or mobile games, tackle technical challenges, and ship polished titles with a collaborative team.

I am a versatile gameplay programmer with 6+ years shipping games across PC and mobile platforms, experienced in architecting and implementing systems from rendering to gameplay. I have led development as a founder and lead programmer, delivered full game pipelines from prototype to release, and solved complex technical challenges including performance optimization and platform support.

My accomplishments include building JSON-based save systems, modular state machines, dynamic minimaps with fog of war, custom physics (collision detection and impulse resolution), and multiple mobile titles published to the App Store. I bring strong proficiency in C#, C++, Unity, tooling and system design, and I work effectively across the full development stack.
