At Infosys, I automate recurring sales and inventory data extraction and transformation with Python and Pandas. I prepare report-ready datasets and build validation scripts so data is consistent before it reaches downstream reporting.
At Tata Consultancy Services, I collaborated with senior engineers on Python and SQL ETL workflows from MySQL to Hive, and developed PySpark data transformations and quality checks. I also maintained a Data Asset Inventory in Collibra to support data governance and discoverability.
