Maxime Labonne is a French ML engineer (Liquid AI, formerly Airbus) and one of the more authoritative independent voices on production LLM engineering. He is the author of LLM Engineer's Handbook (Packt) and publishes some of the most-followed content on LLM fine-tuning and quantisation on the open web.
His CourseFlix listing carries LLM Engineer's Handbook — the book / course companion covering the production-engineering arc of LLM work: data preparation, fine-tuning, evaluation, deployment, and the operational patterns for running LLMs at scale.
Material is paid and aimed at engineers picking up production LLM work as a serious skill. For broader content, see CourseFlix's LLMs & Fundamentals category page.
