Skills & Achievements
I’m a QA engineer with more than 18 years in IT, working in healthcare, FinTech and trading, where a wrong value or a broken workflow has real consequences for users. I combine deep manual testing experience with test automation and a strong focus on QA processes that teams actually use.
Skills
- Test strategy and process: QA setup from scratch, test planning for features and releases, risk-based testing, requirements analysis and test coverage mapping, Definition of Done and release criteria, shift-left practices in agile teams.
- Testing: functional, exploratory, integration, regression, end-to-end and compatibility testing of web and mobile applications (iOS, Android) and REST APIs. Root-cause analysis together with developers.
- Automation: UI and end-to-end tests in Python with Playwright and pytest, API testing with Postman and Swagger, Git and CI/CD pipelines.
- AI in QA: generating test cases and test data from requirements, drafting and refactoring automated tests, failure triage based on logs, reusable prompts and QA workflows.
- Healthcare: HL7 FHIR (resources, profiles, RESTful APIs), regulatory context of medical software (MDR, IEC 62304, ISO 14971), traceability from requirements to test evidence.
- Tools: Jira, Confluence, TestRail, Postman, Swagger, Playwright, Git, browser DevTools.
Achievements
- Set up a mobile OS compatibility testing process: defined the device and OS matrix, test scope and workflow together with developers and QA colleagues, and documented it in Confluence as a team standard.
- Built the QA process for receeve company from zero: test strategy, test documentation, bug workflow and release criteria, reducing production defects by 30%.
- Mapped requirements to tests for Saas and HealthCare products and closed coverage gaps before release.
- Tested trading / payment, Healthcare and Saas platforms where calculation and data accuracy were critical.
- Run my own QA consulting practice, helping clients set up QA processes, review requirements coverage and test APIs.
I care about software people can rely on, clear communication with developers and test suites the team trusts. Based in Stuttgart, available fully remote, fluent English, German B1/B2.
