Key Strengths

  • Built and deployed production RAG-based clinical decision support system for EHR note search and risk insights
  • Reduced LLM hallucinations using RAG + cross-encoder re-ranking and confidence thresholds
  • Scaled retrieval over large EHR datasets using Spark on Databricks (efficient chunking/indexing for low latency)
  • Implemented HIPAA controls (PHI anonymization/tokenization, encryption, RBAC, audit logs/monitoring)
  • Orchestrated end-to-end ML/LLM pipelines with Apache Airflow (dependencies, retries, monitoring) improving reliability and data freshness
  • Translated model uncertainty and outputs into Power BI dashboards for clinical stakeholders; improved adoption and reduced patient readmissions by 18%
