03 / BEHIND THE WORK

From how it looks
to how it plays.

I’m interested in how interactive worlds are built: the systems behind a puzzle, the light on a material, and the feedback that makes a game feel right.

My work spans team game development, independent games, and graphics studies. I’m preparing for graduate study in computer graphics and game development.
