Senior Solutions Architect | AI & Machine Learning Specialist
Jean designs and ships AI solutions — RAG, computer vision, agents, LLMOps and model security — on top of two decades building web, mobile and integration systems that are still running. He founded JBKR in 2006, created AironCore and Apicio, and personally coordinates every project: the person who runs the assessment is the person who writes the code.
