Who I Am

I'm Koln, a full-stack developer from Cebu City, Philippines. I build modern web and mobile applications — Next.js frontends, FastAPI backends, and Flutter apps — with a focus on clean code and great user experience.

Currently a full-time developer at Coolmogo, building AI-integrated production systems with Pydantic AI and SurrealDB. I care about the why behind the code—I follow Git best practices religiously, break complex problems into small pieces, and always reach for the official docs first.
