What I'm looking for

I seek a hands-on QA automation role where I can build/scale test frameworks, drive CI/CD quality, mentor teams, and work on web, mobile, and API testing with a focus on performance and security.

I am an Automation QA Engineer with over 4.8 years of hands-on experience in web, mobile, and API automation testing, building test frameworks from scratch and improving software quality across multiple projects.

I have delivered measurable results — including a 40% reduction in testing time, a 20% reduction in software defects, and a 15% improvement in system performance — by implementing Selenium, Appium, Playwright, JMeter/K6, and CI/CD pipelines with Jenkins.

I collaborate closely with cross-functional teams, mentor junior engineers, and focus on reliable, maintainable test automation, secure API testing, and performance tuning to ensure robust, production-ready releases.
