Hamel Husain is a US ML engineer (formerly at Airbnb and GitHub, now at Parlance Labs), a fast.ai contributor, and one of the most visible independent voices on the production-engineering side of LLM systems — particularly around evals, fine-tuning, and the workflow that connects model training to deployed product features.
His CourseFlix listing carries AI Evals For Engineers & PMs. Material is paid and aimed at engineers and product managers shipping LLM-powered features who need to evaluate model output systematically rather than by gut.
