As a QA engineer working on an e-commerce application, my primary task is to ensure the quality and functionality of the platform. I conduct thorough testing of various features such as product listings, shopping cart functionality, checkout process, payment gateways, user registration, and login systems. I create and execute test cases to validate the application's responsiveness, compatibility across different browsers and devices, and adherence to design specifications. I also perform rigorous testing to identify and report any defects or usability issues, collaborating closely with the development team to ensure prompt resolution. Additionally, I contribute to the continuous improvement of the application by providing feedback on user experience, suggesting enhancements, and participating in regression testing during feature updates or bug fixes. Overall, my role as a QA engineer is crucial in delivering a seamless and reliable e-commerce experience for customers
