I’m Miguel — Tech Lead at Dune Analytics. I write about distributed systems, local LLMs, self-hosting, and whatever else I’m currently debugging at 1am.

Most of the writing lives under Posts. Talks I’ve given, slides, and conference notes are under Papers & Talks. More about me on the About page, or see my resume.
