About me

A little about me

I design and build reliable backend systems and the occasional delightful interface. My work sits between solid engineering practice and applied research — I like problems that need both a clear architecture and a careful experiment.

Lately I have been working with distributed systems, developer tooling, and machine learning pipelines, and writing about what I learn along the way.
