Data Engineer at DTN, LLC building Azure CDC pipelines processing ~45M records daily.

At DTN, LLC, I built real-time CDC pipelines with Azure Data Factory and Oracle GoldenGate across six source domains, enabling low-latency data availability in ADLS Gen2. The pipelines process approximately 45 million records per day.

I developed PySpark transformations in Azure Databricks to validate data across 100+ tables, using Medallion architecture and surrogate-key modeling. I also built batch and streaming pipelines with Azure Event Hubs and Azure Functions.

At Codedrops Tech, I analyzed healthcare claims and operational data with SQL and supported Power BI reporting. In project work, I automated an Amazon Music ETL workflow with Apache Airflow and Docker, and built an end-to-end Azure data engineering pipeline.
