ANSAR Ahmed

I’m a results-driven Test Data Analyst and QA professional with 13+ years of experience across retail and utilities, delivering for major UK clients at Tata Consultancy Services. I focus on turning complex business data into trustworthy outcomes through rigorous validation, reconciliation, and end-to-end testing.

In my current role, I analyse and validate retail data across sales, inventory, pricing, and customer systems for UK clients. I run SQL and PL/SQL queries to ensure data accuracy, completeness, and business rule compliance, and I support functional, ETL, and UAT testing while identifying and reporting data defects.

My work has delivered measurable results: I reduced SAP IS-U billing errors by 15% through systematic BPEM exception analysis and resolution, and I minimised retail POS transaction discrepancies by 12% via functional and UAT testing. I also improved data reconciliation accuracy by 10% using SQL and PL/SQL validation scripts, strengthening confidence in reporting and downstream decisions.

Previously as a POS Test Analyst and Senior Process Associate – SAP IS-U, I owned testing for the POS transaction lifecycle and managed SAP IS-U Meter-to-Cash processes for UK utilities—billing, invoicing, metering, and payment validation. I collaborate closely with UK field engineers, stakeholders, and production support teams, translating real-world operational issues into clear test evidence and effective resolutions.
