Manual QA Tester | Web & Mobile App Testing | Developer Background
Looking for a reliable Manual QA Tester who provides clear, actionable bug reports instead of vague feedback? That's exactly what I do. I specialize in manual testing of web and mobile applications, helping founders and development teams improve product quality before and after release. My goal isn't just to find bugs—it's to investigate them, reproduce them consistently, and provide reports that make them easy for developers to understand and fix. What makes me different is my background as a Full-stack Software Developer. While I test your product like a real user, I also understand how applications work under the hood. When needed, I use Browser DevTools to inspect console errors, network requests, API responses, and other technical details that help identify the root cause of an issue. What I can help you with ✅ Manual & Exploratory Testing Test your application the way real users do to uncover functional issues, edge cases, and unexpected behavior. ✅ Web & SaaS Testing End-to-end testing of user flows including registration, authentication, payments, dashboards, forms, settings, and more. ✅ Mobile App Testing (Android) Real-device testing covering installation, onboarding, responsiveness, usability, and overall user experience. ✅ Regression Testing Making sure new releases don't break existing functionality. ✅ UI/UX & Usability Testing Providing honest first-time user feedback, identifying confusing flows, navigation issues, and opportunities to improve the overall experience. ✅ Bug Reporting Every issue includes clear reproduction steps, expected vs. actual behavior, screenshots or screen recordings, and technical information when relevant (console logs, network requests, etc.). Experience testing • SaaS platforms • AI applications & chat assistants • Web applications • Mobile applications • Payment & subscription flows • Identity verification (KYC) • iGaming & betting platforms • Internal business tools Why clients hire me ✔ I test from a real user's perspective. ✔ I understand how software works behind the scenes. ✔ I communicate clearly and provide organized, developer-friendly bug reports. ✔ I'm reliable, detail-oriented, and genuinely enjoy trying to break things before your users do. If you're looking for someone who will thoroughly test your product, provide honest feedback, and help improve quality — not just click through a checklist — I'd be happy to help!
