About

Most of my day is backend. Schemas, queues, APIs: the stretch between a bottleneck and something you can ship. React and TypeScript on the client, Node and Postgres behind it.

I like the part of the work nobody sees until it breaks, and I like owning a feature from the first sketch to production. These days that includes LLMs, where the hard part is still the data.
