Private RAG for Financial Compliance

The Challenge

A mid-size fintech needed to search and cross-reference 50K+ regulatory documents (MiFID II, DORA, local regulations) without sending sensitive data to cloud APIs. Existing keyword search missed semantic relationships.

Our Approach

We designed and deployed an on-premises RAG system with hybrid search (semantic + BM25), document-level access controls, and a chat interface for compliance officers.

Tech Stack

Qdrant (vector database) BGE-M3 embeddings (local) Mistral 7B (local LLM) FastAPI backend React frontend PostgreSQL (metadata)
