About

I’m a game designer and gameplay programmer focused on building player-centric experiences through strong core-loop design, systems, and rapid iteration. I enjoy turning creative vision into playable mechanics—designing progression, balancing gameplay, and using playtesting feedback to refine features until they feel intuitive and rewarding.

My technical background lets me collaborate effectively with engineers while staying implementation-aware, particularly in Unity and Unreal Engine. I’ve led design direction in cross-discipline teams, programmed gameplay systems and prototypes, and supported live-product iteration. I also bring a proactive approach to AI-assisted workflows to improve production and quality throughout development.
