The Challenge

The starting point.

Clinicians spent an average of 11 minutes per shift searching internal protocols. Off-the-shelf RAG vendors couldn't satisfy the client's HIPAA, audit, and on-prem deployment requirements.

The Approach

What we built.

  1. 01
    Built a hybrid BM25 + dense retriever fine-tuned on medical literature
  2. 02
    Designed prompt scaffolding with citation enforcement and refusal guards
  3. 03
    Created an evaluation suite with 1,200 expert-labeled question/answer pairs
  4. 04
    Deployed via Kubernetes inside the client's existing HIPAA-compliant VPC
