About the way I work

I like the whole thing — the interface people touch, the service behind it, and the infrastructure that keeps it alive.

My best work sits between product thinking and systems engineering: clear enough for a person, sturdy enough for production.

Tools I work with

React · Next.js · TypeScript · Node.js · Python · PostgreSQL · Redis · AWS
