About Me

I'm a game programmer and Computer Science student at the University of Utah. I wrote my first game on Roblox when I was 12 and haven't stopped since. Today I build games in Unity and Unreal Engine, working mostly in C# and C++.

Most recently I programmed for It Was You, an upcoming multiplayer murder mystery on Steam, where I built the character controller and worked on networked gameplay systems. I also co-founded Jetty Games, a 10-person development team, where I work as an engineer and producer. Together we've released a string of game jam projects, from a factory-automation sim to an anomaly-hunting escape room, each one built under a tight deadline.

Before focusing on games, I spent several years as a professional software engineer. That work taught me to track down performance problems, design clean data systems, and ship reliable code on a schedule, all skills I now bring to gameplay programming.
