Chris Alexiuk (online as Chris the Wiz) is a Canadian AI engineer (Developer Advocate at LangChain) and educator focused on the production-engineering side of AI applications — particularly RAG, agentic systems, and the operational disciplines around running LLMs in production.
His CourseFlix listing carries The AI Engineering Bootcamp — a comprehensive applied-AI-engineering curriculum covering the modern LLM-application stack from foundations through to production deployment, including the eval and observability patterns that separate working LLM products from prototypes.
Material is paid and aimed at engineers picking up applied AI engineering as a primary skill. For broader content, see CourseFlix's AI App Building category page.
