Hamel Husain
Made evals the AI engineer's daily discipline
Husain dragged "evals" out of research jargon and into working practice — systematic error analysis and LLM-as-a-judge over vibe checks — and co-published the practitioner guide to LLM evals in The Pragmatic Engineer with Gergely Orosz. His whole thesis is that measurement is what separates a demo from a product you can trust: verification-as-moat, taught hands-on to thousands of engineers.
