Need a QA tester who can find bugs before they reach your users? I provide manual QA testing for websites, web applications, and mobile apps, helping businesses identify functional bugs, usability issues, broken user flows, and edge cases before release. I test from a real user's perspective, not just by checking whether a feature works. I look for what can go wrong across different devices, browsers, user flows, and real-world scenarios. What I can test • Manual & Functional Testing • Website & Web Application Testing • Mobile App Testing • API Testing — Postman & Swagger • Payment Gateway & Transaction Testing • Regression & Retesting • Exploratory Testing • End-to-End (E2E) Testing • Cross-Browser Testing • UI/UX & Usability Testing • UAT Testing • Performance Testing My testing approach I review the requirements and user flows, create practical test scenarios, execute tests, explore edge cases, reproduce issues, and provide clear QA feedback. For every confirmed bug, I provide: ✓ Clear steps to reproduce ✓ Expected vs. actual result ✓ Severity / priority ✓ Screenshots or screen recordings ✓ Environment/device/browser details when relevant I can also test critical payment and transaction flows, APIs, and integrations where accuracy and reliability are important. Tools Jira • Linear • Trello • Postman • Swagger • BrowserStack • Slack • Notion My goal is simple: find issues before your customers do and give you clear information to fix them. If you have a website, web application, mobile app, API, or payment flow that needs testing, send me the details and I can help you define the right testing scope.
