From learning games
to shipping them.

I’m a gameplay engineer with three years of AAA development experience at Treyarch, contributing to Call of Duty: Black Ops 7, Black Ops 6, and Modern Warfare III.

My work centers on Multiplayer gameplay systems and content: building in C++, collaborating across disciplines, and iterating from an early prototype through shipment and live-service maintenance.

Before Treyarch, I studied computer science at the University of Southern California and supported gameplay programming courses as a Course Producer.
