About Me

I love building things people actually use. Most of what I do mixes frontend, backend, and mobile apps, turning ideas into fast, clean, user-friendly experiences. I work a lot with React, Next.js, TypeScript, and Convex.

I'm also really interested in what happens under the surface. I spend time understanding how JavaScript and TypeScript actually work, and sometimes I dig into C and C++ to get a lower‑level perspective. I love seeing how AI systems are built and integrating AI into real products.

No matter what I'm working on, I try to understand the problem, keep the code simple, and leave the project in better shape than I found it. When I'm not coding, I'm usually behind a camera doing filmmaking and photography.
