Manual QA Tester | Web & Mobile

I’m a professional Manual QA Tester with over a year of hands-on testing experience and 500+ bugs reported across web and mobile applications. I have worked on SaaS platforms, marketplaces, e-commerce applications, admin dashboards, business management systems, and consumer mobile apps, testing both individual features and complete end-to-end user journeys. My core experience includes: ✅ Functional & Manual Testing ✅ End-to-End Testing ✅ Exploratory Testing ✅ Regression & Retesting ✅ Smoke & Sanity Testing ✅ UI/UX & Responsive Testing ✅ Cross-browser Testing ✅ iOS & Android Testing ✅ API Testing with Postman ✅ Basic SQL & Database Testing ✅ Bug Reporting & Defect Triage ✅ Test Case Creation & Execution I have experience testing complete workflows from registration and authentication through core functionality, data handling, integrations, and final user actions. I have also performed end-to-end testing of a product consisting of a web application, iOS app, and Android app before release. When reporting defects, I provide developers with everything they need to reproduce and investigate an issue, including clear steps to reproduce, expected vs. actual results, severity/priority, screenshots or recordings, and relevant device/browser information. I’m comfortable working with Jira, Git, Postman, TestFlight, Firebase, MySQL Workbench, and browser DevTools. I don’t simply follow happy-path test cases. I actively look for edge cases, invalid inputs, broken user journeys, inconsistent behavior, permission issues, data problems, responsive issues, and unexpected user behavior. I’m available for both short-term testing projects and ongoing QA engagements and can work independently or as part of an existing development team. If you need someone who will actively try to break your product and clearly communicate what needs to be fixed, I’d be happy to help.
