I’m Jay, a frontend and AI product engineer based in Los Angeles, California. I work across design and development to turn ideas into clear, usable web experiences.

My core stack is React, Next.js, TypeScript and Node.js. I use AI tools as part of an iterative process: prototype, inspect, refine and ship. The interface still has to earn its place.
