Message

At CVS Health, I led a Teradata-to-GCP migration of 38 pricing and claims reports and designed a Bronze/Silver/Gold lakehouse across 15+ sources. I validated parity across 280 pipelines for a zero-disruption production cutover and automated a BigQuery workflow that reduced a manual report from 2–4 days to 1–2 hours.

At Humana, I migrated 200+ Informatica workflows to Azure Data Factory and Databricks, reaching 99.8% job success. Earlier at JP Morgan, I developed Spark pipelines for trade and market data and built streaming applications for fraud detection; I also built PipelinePilot, a data-pipeline incident investigation workflow.
