I help teams deliver stable and high-quality web and mobile applications by identifying critical issues before they reach production. With 4+ years of experience in Manual QA, I focus on improving product reliability, user experience, and release confidence. I have hands-on experience testing web and mobile applications (iOS, Android, HarmonyOS) across the full QA lifecycle: requirement analysis, test planning, test design, execution, regression, exploratory, and API testing. I work closely with Agile teams to ensure clear communication, fast feedback, and high-quality releases. I also have strong experience in backend validation and debugging using SQL, API tools, and browser developer tools, which helps me quickly identify root causes and improve product stability. Key strengths: Mobile Testing, API Testing, Test Design, Exploratory Testing, Regression Testing. Tools: Azure DevOps, Jira, TestRail, Postman, Swagger, BrowserStack, Firebase, Charles Proxy, Proxyman, SQL, MongoDB, Git, Figma. Currently expanding my expertise in UI test automation with Playwright (JavaScript/TypeScript).
