About Felix

I am a freelance UX designer, app and web developer with a degree in Business Informatics (B.Sc., focus on Data Science). By combining analytical thinking, technical know-how, and creative design understanding, I develop digital products that are both functionally convincing and user-centered.

I work with a clear focus on the user:
My goal is to design digital experiences that are intuitively understandable, visually appealing, and technically stable. I place great importance on clear information architecture, micro-interactive details, and performant implementation.

My focus areas:
• UX / UI Design – from research to wireframes to high-fidelity prototypes
• App development with Flutter (iOS, Android & Web)
• Firebase integration (Auth, Firestore, Storage, Functions)
• Web design & web development (responsive, modern, SEO-friendly)
• Product strategy, prototyping & MVP development

I work remotely or hybrid, am organized, have strong communication skills, and place great importance on transparent collaboration. My clients particularly appreciate that I always justify design decisions based on data and users – and that I implement projects creatively and technically reliably.

What you can expect from me:
• Clear communication & structured processes
• Clean, maintainable codebase (Flutter / Firebase)
• Design solutions with a focus on usability & business goals
• Adherence to deadlines and independent working style
• Optional: accompanying video content or explanatory animations for your product

I am happy to support you in the conception, design, and implementation of your digital product – whether it's an MVP, a complete app project, or the optimization of existing systems.
