Santiago Valdarrama is a US ML engineer and the founder of ml.school — focused on the production-engineering side of ML systems rather than the academic theory side. His material covers the kind of engineering work most ML courses skip: deployment, monitoring, retraining, and the realities of running ML in production.
His CourseFlix listing carries Learn to Build Machine Learning Systems That Don't Suck. Material is paid and aimed at engineers transitioning into production ML work.
