At Peak Performance Apps GmbH, I designed and implemented test cases and plans for web and mobile applications, and conducted accessibility testing. I worked with clients including ARD Quiz Platform, KiKA Quiz App, 1LiveKrone, Tagesschau, and Mercedes-Benz Media.

I used Postman and Swagger for API validation and documentation, and X-Ray for test case management. I also managed ticketing, sprint planning, and defect tracking through Jira and Confluence in Scrum and Kanban processes.

At Appsfactory, I worked on test strategy, execution, and accessibility testing for web and mobile applications, including projects for ARD Quiz Platform, KiKA Quiz App, DiskutierMitMir, and Beurer.

Earlier, I contributed to project delivery and development at DroidSolutions GmbH and Green-m Interface Design GmbH, and to image-processing research at Fraunhofer IWU. I hold an ISTQB® Foundation Level certification.
