At Cigna, I build governed data platforms that bring clinical, claims, and genomic data together for oncology and population health. I also developed a RAG workflow for clinical notes, from embedding generation and vector retrieval to automated summaries with human review.
At Optum, I modernized healthcare ETL pipelines and built dbt models for reporting, provider analytics, and research. I also developed AI-ready pipelines for risk scoring and claims document intelligence using embeddings and vector retrieval.
Earlier, I developed insurance data pipelines at Liberty Mutual and backend services at Bank of America. My work spans cloud data engineering, healthcare interoperability standards, and secure data governance, supported by AWS, Google Cloud, Terraform, and Databricks certifications.
