At Cigna, I develop data pipelines for customer, policy, claims, billing, and operational datasets. I designed Bronze, Silver, and Gold layers in Databricks and Delta Lake, improving downstream data reuse by approximately 30%.
At Wells Fargo, I developed data workflows for consumer banking, processing more than 10 million customer, account, and transaction records daily. I also modernized selected MapReduce workloads with PySpark and Scala, reducing batch execution time from approximately six hours to under three.
At Western Union, I developed and maintained pipelines for transaction, payment, and remittance data, and supported AWS-based ingestion. Earlier, as a Database Administrator at Netflix, I supported MySQL, PostgreSQL, and SQL Server databases, including query optimization, backups, and replication monitoring.
