At The Hartford, I lead data engineering for insurance claims, policy, underwriting, pricing, and risk analytics. I build AWS and Snowflake data solutions, including pipelines and warehouse models, and improved batch performance by approximately 35%.

Previously, I supported healthcare data workloads at Humana Inc. and retail data pipelines at Target, working with Azure, Databricks, Spark, and BigQuery. At Dell, I developed Python APIs and backend services for enterprise infrastructure and storage platforms.
