I am Thomas Sieber, a senior QA/test automation engineer with over 15 years of experience delivering test automation and performance engineering for enterprise systems across banking, logistics, public transportation, government and medical technology. I specialize in API testing, mocking/service virtualization, CI/CD integration, and scalable load/performance testing. I am ISTQB Advanced certified and approach every project with an engineering-driven mindset. I enjoy turning complex requirements into robust automated tests and reliable performance benchmarks, collaborating with cross-functional teams, and building reusable test assets that scale with growing systems. My work spans Java-based stacks, containerized environments, and cloud platforms (AWS/Azure), and I thrive in challenging, fast-paced domains.…I am Thomas Sieber, a senior QA/test automation engineer with over 15 years of experience delivering test automation and performance engineering for enterprise systems across banking, logistics, public transportation, government and medical technology.
