At TECH MAHINDRA, I lead Azure data engineering work for Bon Secours Mercy Health, delivering data ingestion and consumption solutions using Medallion architecture on Azure Databricks. I designed Azure Data Factory pipelines and Databricks workflows, and supported migration from Azure Synapse to Databricks.

I also developed automation for applying SQL schema upgrades across Delta tables and built an AI-based solution to generate column descriptions. I work directly with clients on requirements and delivery, and serve as Release Manager for production reviews and CI/CD deployments.
