At MattsenKumar, I led a large-scale seller and vendor data quality and enrichment project for Flipkart. I designed T-SQL validation frameworks and improved dataset hygiene by 0.7% through cleansing, de-duplication, parsing, and categorization.

At Proziod Analytics, I audited and validated multi-source datasets, supported data enrichment and integration, and created dashboards with SQL, Power BI, and Tableau. Earlier, at Tata Consultancy Services (TCS), I resolved energy consumption data issues and supported reporting and data extraction.
