Texts about AI and crypto

This is my personal technical site.

I write notes and essays about AI engineering, crypto, proof systems, and product work.

I’m Omar U. Espejel. I work on AI and crypto at Starknet Foundation. Before that I worked on crypto at StarkWare and machine learning engineering at Hugging Face.

A lot of the pieces start as research in progress. I try to make the idea clear enough that someone else can inspect it, reproduce it, or disagree with it.
