QA Engineer | Software QA Automation | Manual Testing | AI QA Tester

Top Rated Plus QA Tester with 4+ years and more than 1,000 hours on Upwork, specializing in manual testing and Playwright automation for web and mobile apps. As a QA Engineer / QA Tester I find release-blocking bugs while they're still cheap to fix, and deliver clear, reproducible Jira reports your developers can act on the same day. I've tested SaaS platforms, internal tools, and ERP systems through fast release cycles, keeping quality high while the product keeps shipping. ➤ What I Do ✅ Manual Testing: functional, regression, smoke, and UI/UX checks for new features and full releases ✅ Playwright Automation: stable E2E suites that end repetitive manual regression cycles ✅ API Testing: Postman collections, response validation, and SQL data checks ✅ Web & Mobile App Testing: cross-browser and cross-device coverage (iOS, Android, desktop) ✅ Bug Reporting: reproducible Jira tickets with steps, environment, screenshots, and video ✅ Test Case Design: structured documentation for full coverage, UAT, and exploratory testing ➤ Industries ✅ Healthcare & Health-Tech: patient portals, telehealth, EHR/EMR workflows, HIPAA-aware testing ✅ SaaS platforms, internal tools, and ERP systems ➤ Why Clients Work With Me ✅ I test like your most demanding user and flag unclear requirements before they burn dev time ✅ Fast communication, organized documentation, no drama ✅ Honest feedback: if something isn't worth automating, I'll say so ➤ Tools & Process Playwright, Selenium, Postman, Jira, TestRail, ClickUp, Trello, SQL, Git, GitHub Actions, Docker, BrowserStack | Agile, Scrum, CI/CD, SDLC 📩 Message me with what you're building and I'll send back a short, custom test plan.
