Led Android QA for a social media app, covering manual testing and automated tooling for mobile and backend services. Reduced production defects to less than 20% (300 found, 199 resolved) and improved automated regression efficiency and time by 40% by integrating Appium suites into GitHub Actions with Saucelabs and multi-remote testing.

Designed and executed 462 manual test cases for Android/iOS (functional, regression, integration) and built k6 load tests simulating match-day traffic with 200 VUs. Validated REST APIs with Postman/Newman against p95 thresholds (<2 seconds), logged 200+ defects in Jira, and produced test entry/exit reports.

Performed manual functional, smoke, regression, and end-to-end testing for an AI-driven job matching web platform. Validated CV auto-alignment, one-click applications, generated cover letters, and serverless backend workflows; logged critical bugs to stabilize the app before launch.

Built a modular Playwright (TypeScript) testing framework for web-based SaaS products, reducing regression effort by 70%. Conducted functional, regression, integration, and end-to-end testing, improved CI/CD via GitHub Actions, integrated automated workflows with TestRail and Jira, and mentored junior testers while tracking QA metrics.

Delivered end-to-end manual and automated testing for e-commerce payment gateways on Android/iOS, including API testing and load testing. Achieved a 100% defect closure rate through clear bug reporting.
