About
NLP/ML engineer with hands-on healthcare and support-ticket text experience, building clinical-note structuring and semantic linking systems using spaCy, BERT clinical embeddings, and FAISS. Emphasizes production-grade delivery (Airflow/Databricks, PySpark, Docker, AWS/FastAPI/Lambda) and rigorous validation via clinician-labeled datasets, retrieval metrics, and user feedback.

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
