Key Strengths

  • Built NLP pipeline to structure clinical notes using spaCy + BERT clinical embeddings
  • Designed relationship-mapping layer combining embeddings, structured clinical features (ICD/med classes/time windows), and clinician-labeled validation
  • Hybrid entity resolution approach (deterministic + probabilistic + embedding similarity) with precision/recall/pairwise F1 evaluation
  • Improved semantic search/data linking using FAISS vector index and domain fine-tuning; measured gains with offline metrics and user feedback
  • Production-grade Python workflow engineering (modular design, orchestration with Airflow/Databricks, distributed processing with PySpark, containerized AWS deployments)
  • Clear prototype-to-production process using retrieval metrics (precision, MRR), stability checks, and stakeholder alignment
