What I'm looking for

I'm seeking a QA Engineer, Software Tester, or hybrid QA and application-development role where I can test web and mobile products, support automation, collaborate with product teams, and contribute to building reliable applications.

At Optitrust GmbH, I plan and execute manual testing for web and mobile functionality, usability, compatibility and regression coverage. I create test cases, document defects with clear reproduction steps, retest fixes, and collaborate with developers and product stakeholders.

Through Digital Solutions Studio, I build web, mobile, and Windows desktop applications for booking, ordering, education, and business operations. My work includes platforms for work orders and inventory, appointment booking, children’s learning, bakery production, and mobile food ordering.

I use ChatGPT and Codex to support implementation, refactoring, and debugging while retaining responsibility for requirements, technical decisions, testing, refinement, and deployment. I work with React, React Native, Firebase, C#, .NET, WPF, Selenium, and Cypress.
