At TCS, I work on United Overseas Bank’s enterprise data repository for OTC derivatives trading, supporting financial products and automated reporting. I reduced ETL job runtimes by 40% through performance tuning and supported more than 60 production workflows processing over 2.5 million records daily with 99.5% SLA compliance.
For the Media Reach advertisement-domain project, I developed end-to-end ETL pipelines and helped shorten batch processing windows from six hours to three and a half. I also implemented Python-based data quality checks that reduced data errors by 85%.
On the UHG Insurance Limited data warehouse project, I provided L2/L3 production support, monitored ETL jobs, and modified SQL queries and Informatica code. My work spans banking, advertising, and insurance data integration.
