Summary

I'm a senior game programmer with a strong background in proprietary game engines, editor tooling, procedural content, UI, audio, multiplayer, and game systems.

My independent work focuses on gameplay, design, experimentation, and learning new things, including game jams, prototypes, and a current puzzle game in a custom C/C++ engine.

I enjoy wading into systems and ambiguous problems, learning enough to figure out what matters and finding simpler solutions, especially if it means deleting a bunch of code, or making tools and systems more joyful.
