I’m a Manual Mobile App QA Engineer & Product Minded Tester who helps developers ship cleaner, more reliable apps.
Bugs don’t scare users away unexpected ones do. I bring a structured QA mindset combined with real user and product thinking to catch the issues that matter most before they reach your users or hurt your ratings.
I don’t just tap around and hope something breaks. I design and execute test scenarios that cover the full user journey, from happy paths to edge cases developers rarely think to test, while also identifying product and usability issues that impact the overall experience.
What I test:
- App functionality & feature validation
- UI/UX consistency (layout, spacing, alignment, responsiveness)
- Navigation flows & usability gaps
- Input validation & form behavior
- App crashes, freezes & unexpected errors
- Device & OS compatibility
- Regression testing after updates or fixes
What you get:
- Structured, easy-to-read bug reports
- Clear steps to reproduce every issue
- Severity ratings to help prioritize fixes
- Screenshots or screen recordings with each report
- A test summary with quality assessment and product observations
- Fast turnaround and clear communication throughout the project
Whether you need a quick smoke test or a full regression cycle, I approach every project with attention to detail and a focus on the user experience. If you're looking for a QA Engineer who finds the issues that matter before your users do, I'd love to help.
