FastAPILangChain / LangGraphVertex AI (Gemini)ChromaDBReactTerraform / Cloud Run

Challenge — Organizations want a trustworthy internal AI — one that answers from their own knowledge, refuses to hallucinate, and leaves an audit trail for compliance.

Solution — A full production architecture: RAG core, LangGraph agent orchestration, input/output guardrails, audit logging, and a React chat UI — deployable to Google Cloud Run via Terraform, with versioned prompts and observability.

Result — A reference-grade assistant: grounded, governed, and observable — the blueprint I deploy for regulated and enterprise clients.
