The final discipline every serious AI developer in 2026 needs: how to put an LLM on top of real business data without it hallucinating columns, joining wrong tables or leaking data across access boundaries.
Learn the semantic layer as a discipline, build one with dbt Semantic Layer, wire it to an LLM through MCP and take a working system through governance, versioning and observability.
Ends with a capstone building a trusted AI-on-data system for Alpine Financial, a fictitious SA fintech.
