As a dedicated QA specialist, I have hands-on experience in manual testing across various platforms, including web, mobile, and games. My key responsibilities include conducting cross-browser and cross-platform testing, identifying bugs, and creating detailed bug reports. Using tools such as Jira, TestRail, Mantis, and TestLink, I document and manage test cases to ensure comprehensive test coverage and effective bug tracking. My expertise extends to developing test cases and checklists tailored to different testing needs, including mobile games, which allows me to maintain thorough quality control. I am skilled in both Postman and SoapUI for API testing, ensuring that all software components are seamlessly integrated.
