Description

I am a passionate Mobile App Developer with a focus on React Native and TypeScript. In addition to my own financial app Budget For Nomads, I have worked in various teams on the implementation of complex mobile applications. From scientific data projects to a commercial trading news app for wikifolio.

Through my previous projects, I have gained extensive experience in handling APIs, CI/CD, automated testing, cross-platform development, and agile collaboration. My focus is on implementing UX-based front-end. I bring a friendly and motivated atmosphere to the team and have an eye for detail.
