02 / A LITTLE ABOUT ME

Curious by nature.
Programmer by craft.

I’m a game programmer who enjoys getting into the details: how a world renders, how a mechanic feels, and how a simulation stays in sync.

I grew up in New Jersey and graduated from George Mason University in 2017 with a degree in Computer Game Design. My work spans VR, graphics programming, networked simulation, and tools that make creating easier.
