What I'm looking for

I’m looking for a QA role where I can own end-to-end testing (functional, regression, UAT), expand automation with a framework, and partner with engineering and product to ship high-quality releases driven by clear metrics and defect traceability.

I’m a software QA engineer with more than 10 years of experience, passionate about solving users’ problems and ensuring software meets expectations. I apply testing principles throughout the Software Development Life Cycle (SDLC) and focus on clarity, quality, and accountability.

I design, create, and execute test cases across functional, regression, UI/UX, and acceptance testing (UAT), including Agile/Scrum environments. I also track software-related metrics and bugs to drive improvement opportunities, using tools like Jira for defect management and traceability.

I’ve led pixel-perfect testing for native iOS applications, supported the transition from manual to automated testing, and contributed to test automation framework implementation. From load testing with JMeter to API testing and BDD scenarios with Cucumber, I help teams deliver high-quality releases with confidence.
