I’m a Top Rated Plus Senior QA Engineer specializing in Manual Testing, Software QA, Mobile App Testing, Web Testing, Functional Testing, Regression Testing, API Testing, and QA Automation. With 15K+ Upwork hours, 46 completed jobs, 100% Job Success, and 5-star client feedback, I’ve worked with product teams that need more than someone simply clicking through screens. I test complete user journeys, business logic, integrations, permissions, edge cases, devices, browsers, APIs, and real-world failure scenarios. My focus is simple: find what can break, explain exactly why it matters, and give your development team enough information to reproduce and fix it quickly.
