I've supported Tata Consultancy Services on AbbVie data workflows, moving data from Amazon S3 to Oracle and optimizing PySpark jobs on Amazon EMR. I troubleshoot pipeline failures, investigate data mismatches, and implement lasting fixes across distributed ETL processes.
I build automation for reporting, data retention, file validation, and Inventory at Risk processes using Python, SQL, Oracle, Redshift, and AutoSys. My work helps business stakeholders identify discrepancies early while improving pipeline stability and storage efficiency.
Earlier, I developed Django web products at Infocom Network, including tradeindia.com, GetDistributors.com, Tradekhata, and internal portals. I delivered catalog, invoicing, subscription, notification, verification, and WhatsApp-based sharing features, while resolving UI and application issues.
