SDET with 13 years building scalable UI/API automation and CI/CD quality pipelines that accelerate reliable releases.
GermanyWhat I'm looking for
I’m a Software Development Engineer in Test with 13 years’ experience in test automation, QA strategy/planning, and CI/CD pipeline optimization. I design scalable frameworks for UI and API testing and translate quality goals into measurable outcomes.
I’ve built and maintained automation solutions across Web, API, and Desktop contexts—leveraging Java, C#, and JavaScript. I’ve implemented BDD/TDD approaches (Cucumber/SpecFlow), API automation with RestSharp, and reliability-focused test design using Page Object Model and robust mocking (WireMock).
I also prioritize execution efficiency and release readiness by defining quality metrics, scaling regression suites, and improving CI/CD performance. Examples include integrating device modules to raise test efficacy by 30%, scaling regression by 25%, and reducing execution time by 10%, while mentoring junior engineers and driving continuous quality improvements.
