At Pfizer, I designed a Medallion Lakehouse for clinical, quality, and supply chain analytics, with automated Bronze, Silver, and Gold data layers. I also built batch and near-real-time pipelines processing 400K+ assay events daily.

I’ve developed governed data products and modernized legacy ETL workflows across healthcare and financial data platforms. At Pfizer, I prototyped an MCP interface and LLM-based data summarization using governed clinical datasets, and mentored a team of five engineers.
