I’m a QA Engineer with 6+ years of commercial experience owning quality across enterprise financial systems and data-critical integrations. I built Selenium-based regression automation frameworks and am hands-on with Postman for REST API validation, SQL for backend data integrity, and Azure DevOps for CI/CD release pipeline support. I’ve led end-to-end STLC ownership from test strategy and automation design through to release sign-off across 20+ release cycles in fast-moving Agile teams. My impact includes a 50% reduction in manual regression effort through automation and a 60% uplift in program visibility via structured defect dashboards and traceability. I thrive in distributed teams, collaborating directly with engineers and product managers to make quality a shared outcome, not just a gate.
