About

I'm dongquoctien — a full-stack developer based in Vietnam. I enjoy products that respect the user's time, systems that age gracefully, and tools that make the boring parts of software delightful. Most of what I publish here is open source.

Lately I spend a lot of time at the seam between AI agents and existing software — building Model Context Protocol servers so language models can do real work in the systems people already rely on.
