LangGraph compliance-review agent for financial services. Citation-grounded determinations against a regulatory rulebook, conformal abstention to human review, Slack HITL approval gates, examiner-grade hash-chained audit log. Eval reports false-negative rate, not just accuracy.

Interactive workshop for implementing RAG systems using Anthropic's Citations API. Focused on advanced patterns, system architecture, and production deployment for senior engineers.

Production RAG pipeline on FinanceBench: hybrid BM25+dense+RRF+Cohere Rerank, Anthropic Contextual Retrieval, conformal abstention (Yadkori 2024), Citations API grounding, triple eval (RAGAS+HHEM+DeepEval). Every eval number is reproducible and CI-gated.
