Hire the Best Regression Testers

Senior manual QA tester for mobile apps (iOS & Android), web apps, Shopify stores, SaaS dashboards, and APIs. 24+ Upwork contracts, 5.0 average rating, 100% Job Success. ISTQB certified. Real devices, never emulators. Here's the call I save you from: your app is two weeks from launch. Your devs swear it's clean. Then a beta user finds a checkout bug that's been there for months, and it's all over your support inbox by Monday. Before Upwork I did QA for Bell Canada (telecom), Ubisoft (Space Junkies VR), Abbott (health tech), and FLO EV Charging. On Upwork I've tested Shopify stores, SaaS platforms, native iOS and Android apps, Steam games, and beta programs. What you get: - Reproducible bug reports with steps, screenshots, and screen recordings - Severity ratings (Critical, High, Medium, Low) so your devs know what to fix first - Test cases and reports in your tool: Jira, TestRail, ClickUp, Notion, GitHub Issues, or a clean doc - Real-device testing on iPhone 15 (iOS 26), Samsung Galaxy S24 FE (Android 15), Windows, and macOS - 0-4 hour response time, overlapping US East, UK, and EU hours What I test: mobile apps, Shopify checkout flows, web apps and SaaS dashboards, payment flows, APIs (Postman), games (Steam, mobile, VR), and beta programs (TestFlight, Google Play closed testing). Testing types: functional, regression, smoke, exploratory, UAT, cross-browser, cross-device. Recent client feedback: "Provided a thorough testing of our game with a very fast turnaround time." / "Super efficient, collaborative, and easy to work with." Send me your build, staging URL, or TestFlight invite and I'll come back with exactly what I'll test, the timeline, and what lands in your inbox. No surprises, no padding.
