Built an end-to-end medical-orientation RAG assistant on a two-stage hybrid retrieval architecture (FAISS + BM25 + cross-encoder reranking), served via FastAPI with rule-based symptom routing and emergency red-flag detection.
Designed an evaluation framework over a 1,000-question golden dataset with an independent LLM judge scoring faithfulness and hallucination, which surfaced a safety-routing bug and lifted emergency recall from 50% to 100%.
Hardened the assistant for production: prompt-injection filtering ahead of every LLM call, deduplication, version-safe index rebuilding, and a strict advisory-only workflow that defers to physicians and emergency services, covered by a pytest suite.
Built a two-stage chest X-ray triage pipeline (ResNet50 classifier + YOLOv8 detector) reaching 96.9% accuracy and 99.7% AUC on a 522-image held-out test set.
Designed a doctor-in-the-loop clinical workflow that persists physician corrections as structured data for monitoring and retraining.
