Axel S.

Senior QA Automation Engineer

Hi, I’m Axel Saballos, a seasoned QA Engineer with a proven track record of designing and implementing robust quality assurance strategies tailored to fast-growing organizations. I specialize in developing robust QA solutions both manual and automated and have successfully built custom automation frameworks from the ground up using tools like Playwright, WebdriverIO, and Selenium. My approach is not just technical it's strategic. I create test architectures that are scalable, maintainable, and traceable from business requirements to test results. Tools like Jira and Zephyr allow me to ensure end-to-end traceability, linking user stories and acceptance criteria to test cases, execution cycles, defects, and metrics. This not only enhances visibility for stakeholders but also aligns QA efforts directly with business value and compliance standards. Additionally, I work with technologies like MySQL to validate data integrity during testing, ensuring a full-spectrum QA approach across layers of the application. More than just executing tests, I focus on building QA teams, processes, and cultures from the ground up, establishing a clear roadmap for quality across the organization. If you're looking for someone who can lead QA strategy, implement tailored testing frameworks, and deliver full traceability throughout your development lifecycle, I’d be thrilled to contribute my experience to your team.
