Building software at the intersection of the web

I'm a software engineer who likes shipping useful systems: mobile apps, admin platforms, backend services, security automation and GenAI integrations. Recently that has meant live monetization, faster streaming playback, secure workflows and AI subtitle translation. On the side, I'm studying physics and trying to make sense of the universe.

Two trajectories,one observer.

Hi, I'm Kevin. I've spent the last 4+ years building mobile, web and backend systems — mostly with TypeScript, React/React Native and Node, plus a healthy dose of Postgres. I enjoy figuring out how to keep systems simple as they grow, and I'm a big believer that clarity in code matters more than cleverness.

On the side I'm studying for a Bachelor's in Physics. The same curiosity that pulls me toward Schrödinger's equation is what got me into distributed systems in the first place — both are about modeling things precisely enough to actually predict what they'll do next.

If I could hop on a ship to another galaxy tomorrow, I probably would. Until then, I'm happy building, reading Feynman, and learning new things one bug at a time.
