What I'm looking for

I'm looking for a QA role where I can validate web, mobile, API, and database workflows, grow my automation skills, and apply my cloud operations background to release quality and root-cause investigation.

I've executed 400+ test cases and reported 150+ functional, UI, API, mobile, and data defects across Urban Routes, Urban Lunch, Urban Grocers, and Urban Scooters QA projects. I validate end-to-end workflows using manual, exploratory, regression, API, database, and UI automation testing with Jira, Postman, SQL, Python, Selenium, and Pytest.

Before QA, I supported enterprise operations at IBM/Kyndryl, including an on-premises-to-AWS migration with 100% availability, proactive AppDynamics monitoring that reduced critical response times by 25%, and multi-platform incident management. I bring this infrastructure background to root-cause investigation, release validation, and clear collaboration across technical and business teams.
