About Mercedes

With over 4 years of experience as a QA Engineer, I am passionate about ensuring the quality and functionality of software products. I have a strong background in analyzing, reviewing, and testing requirements, user stories, and acceptance criteria, as well as designing and implementing test cases and procedures. I am also proficient in using tools such as Jira, Confluence, Postman, Selenium, and Behave to manage, execute, and automate tests.

As a QA Engineer I actively participate in refinement meetings with the Product Owner, identify and document test conditions, create detailed test execution schedules, flag bugs and report issues, and collaborate with the development team in an Agile environment. I am always eager to learn new skills and methodologies in the field of Quality Assurance, and I hold the ISTQB Certified Tester Foundation Level credential.

My goal is to continuously improve and innovate in my domain, while contributing to the success and satisfaction of the clients and users.
