Message

At UnitedHealth Group, I modernize an enterprise healthcare data platform that processes 10+ TB/day. I led the CDC and streaming ingestion workstream from architecture through production rollout, cutting data sync latency from four hours to two.

I also developed RAG-ready healthcare data pipelines for semantic retrieval and built governed Lakehouse datasets for analytics and AI use cases. Previously, at CNA Insurance and Fifth Third Bank, I developed cloud data platforms and pipelines for insurance and banking analytics, including near-real-time claims ingestion and large-scale batch processing.
