I’m a versatile QA engineer with hands-on experience in both manual and automation testing across mobile and web platforms. I recently led the design and implementation of a mobile automation framework using Python, Pytest, and Appium, integrated with BrowserStack SDK, Jira, and Jenkins CI. With a background in Java, TestNG, and working knowledge of Selenium, I’ve contributed to test coverage and stability across a range of projects. I’m also a long-time Linux user (15+ years), bringing confidence in scripting, debugging, and working in developer-centric environments. I work well in Scrum/Agile teams and actively support shift-left testing practices, embedding quality early in the development lifecycle. Whether it’s exploratory testing, test case design, or building scalable automated frameworks, I bring a quality-first mindset and a collaborative, solution-driven approach.…I’m a versatile QA engineer with hands-on experience in both manual and automation testing across mobile and web platforms.
