About

Bad data doesn't announce itself. It quietly corrupts reports, misleads decisions, and surfaces at the worst possible moment — usually in front of a client or an executive. Preventing that is what I do. I'm a QA & ETL Test Lead with 10+ years of experience making sure the data that reaches dashboards, MIS reports, and business users is accurate, complete, and trustworthy. I've worked across financial services, insurance, and taxation domains — environments where a wrong number isn't just a bug, it's a compliance risk or a business decision gone wrong. My work sits at the intersection of data and quality. That means source-to-target validation, ETL pipeline testing, SQL-based data reconciliation, report and dashboard validation, and end-to-end SIT/UAT coordination. I've led migrations from JasperSoft to Qlik Sense, built test strategies for large-scale DWH implementations, and managed teams through complex, high-stakes releases. What I bring beyond the technical side: I understand what business users actually need from their data. That makes me effective not just as a tester, but as someone who bridges the gap between development teams and the people who depend on the output. Currently open to ETL Testing, DWH Testing, and QA Lead roles where data quality isn't an afterthought. If you're hiring or building a team in this space — let's talk.
