What I'm looking for

I’m seeking Data QA, BI testing or QA Lead roles where data accuracy and analytics-driven quality reporting matter.

At Tata Consultancy Services, I led end-to-end QA for 23 Nielsen IMS applications, covering test planning, strategy and execution. I used PICT to design regression scenarios that improved coverage and reduced redundancy, and received the TCS GEMs award for zero production defects.

At Vetri Technology Solutions, I applied SQL, Python, Power BI and Tableau to data analysis, validation and reporting. For the Vetri AI OS project, I tested role-based access and found two access-control bypasses, which were fixed using PostgreSQL security controls.

My work spans banking, e-learning and media, including regression testing for the RealizeIT e-learning app and development for the CITICARDS Embossing Project. I’ve also completed AI Data Analytics training and hold an ISTQB Certified Tester certification.
