Experience

Senior QA Engineer

Delivering robust, high-performance applications as a senior QA engineer. I designed and implemented scalable automation frameworks using Playwright, Selenium, and Coded UI. I created detailed test plans, wrote and executed manual and automated test cases, and performed API testing with Postman. I also actively collaborated with cross-functional teams to identify risks early in the SDLC, ensuring timely and high-quality releases.

Additionally, I contributed to performance testing using Visual Studio Team Services (VSTS) Ultimate and IBM Rational Performance Tester, and conducted basic security validations.

Finally, I mentored junior QA members, set up CI/CD pipelines via Jenkins and Azure DevOps, and promoted QA best practices throughout the team. My work ensured faster feedback loops, reduced defects, and significantly improved product stability and customer satisfaction.
