Architected a HIPAA-compliant hybrid RAG pipeline using Claude 3.5, pgvector with dense+sparse re-ranking, and a low-latency Next.js 15 clinical dashboard.
In emergency medicine, every minute spent searching through fragmented medical records increases patient risk. Aura Health approached Hopfield Labs to build an automated intelligence layer capable of indexing clinical notes, laboratory results, and prescription histories in real time.
We engineered a deterministic RAG architecture utilizing dense semantic embeddings generated via BioClinicalBERT alongside BM25 sparse keyword indices. A cross-encoder re-ranking stage ensures that critical contraindications always rank highest.
The result was deployed on dedicated HIPAA-compliant infrastructure, delivering sub-800ms query latency across 1.4 million patient records.
