Manual QA Tester | Web, Mobile, API & SaaS Testing | Automation, AI QA
Your product may look ready on the surface, but real users test it differently. They switch devices, take unexpected paths, enter unusual data, use slow connections, and reach integrations your team may not test every day. That is where I come in. I help SaaS, web, and mobile teams catch usability gaps, functional problems, device-specific behavior, weak edge-case handling, and API inconsistencies before customers experience them. I am a QA Engineer with 4+ years of professional experience testing web, iOS, Android, and desktop applications. My work combines detailed manual testing with automation testing support using Cypress and Playwright, API validation through Postman, and practical cross-browser and real-device testing. Clients hire me when they need more than someone who clicks through screens. I study the product, understand the user journey, test the happy path and the uncomfortable paths, document findings clearly, and help the team know exactly what should be checked before release. I can support you with: • Functional, regression, smoke, exploratory, integration, end-to-end, usability, and UI/UX testing • Web application testing across browsers, screen sizes, and user roles • Mobile app testing on real iOS and Android devices • API testing and validation with Postman • Cypress and Playwright automation testing support for repeatable regression coverage • Test plans, test cases, checklists, release testing, and acceptance testing • Clear Jira, ClickUp, Trello, Linear, or Google Sheets reporting with screenshots, recordings, expected results, actual results, and reproducible steps • Performance testing using JMeter and LoadRunner • CI/CD testing support and collaboration with developers in Agile teams I test on real devices, including Windows 11, macOS, iPhone XS, iPhone 14 Plus, iPhone 16 Pro Max, iPad 10th Generation, Google Pixel 7, and Samsung S22. This helps me validate the product experience beyond browser emulators alone. My recent clients have specifically appreciated my detailed reports, screen recordings, fast communication, reliable execution, and ability to explain findings clearly so developers can act on them without back-and-forth. Whether you need a complete QA pass before launch, ongoing regression coverage, mobile app validation, API testing, or an extra QA resource for your team, I bring a structured process, strong product thinking, and careful attention to user experience. Let’s make sure your users meet a polished product, not unfinished behavior.
