I help teams release high-quality web and mobile applications by identifying bugs, improving user experience, and validating real user workflows before they reach production. Iโ€™m a Software QA Tester currently working with Bell Canada, and I have also supported projects related to Virgin. I test applications used by large, real-world user bases where reliability and clarity are critical. My approach is simple: I test like a real user, not just a tester. I go beyond clicking through features and focus on how the product actually behaves, feels, and performs in real scenarios. ๐Ÿ” What I can help you with: โ€ข Manual testing for web and mobile applications โ€ข End-to-end user flow testing (real usage scenarios) โ€ข Bug detection with clear reproduction steps โ€ข UI/UX and usability feedback โ€ข Regression and functional testing โ€ข Accessibility testing (basic usability & clarity checks) โ€ข Mobile testing on real devices ๐Ÿงช What you get: โ€ข Clear, structured bug reports (steps, expected vs actual, screenshots) โ€ข Honest feedback on usability and user experience โ€ข Identification of critical issues and edge cases โ€ข Reliable communication and on-time delivery ๐Ÿ› ๏ธ Tools & Environment: โ€ข Jira โ€ข Agile / Scrum workflows โ€ข Chrome DevTools โ€ข Real devices (mobile & desktop testing) ๐Ÿ’ก Why clients choose me: I focus on what actually matters before release: Broken flows Confusing UX Real user frustration points I donโ€™t just report bugs, I help you understand what needs to be fixed first and why. If youโ€™re looking for a detail-oriented QA tester who can quickly understand your product and provide clear, actionable feedback, Iโ€™m ready to help.

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.
