About

I'm a Senior Product Designer and Product Manager with 15+ years of experience designing digital products across B2B SaaS, enterprise software and B2C platforms.

I've worked on everything from complex PIM and CRM systems to mobile products and large consumer platforms. I specialize in simplifying complex workflows, building scalable design systems and working closely with product and engineering teams to turn difficult problems into usable products.

My core tools are Figma and the full UX process from user research and wireframing to interactive prototypes and design systems, applied across B2B SaaS, e-commerce, mobile apps, and enterprise platforms in the Ruhrgebiet and beyond.

Outside of work, I enjoy spending time with my family, traveling, cooking, playing piano, anything related to Tolkien, animals, and exploring new ideas.

My Design Process

Understand

This step involves deeply understanding stakeholder and user needs, market trends, and the competition at each stage of the project.

Research

Seek to understand user behaviors using surveys, interviews, task analysis, and personas. Based on the scope of the project, research is often iterative.

Analyze

Look for patterns to create user personas, define requirements, and evaluate features for future decision-making.

Ideate

Generate ideas through sketching workshops, prototypes, and flows to visualize solutions backed by data.

Prototype

Turn ideas into design through testing and feedback, ensuring usability improvements before final build.

Validate

Final evaluation of the project with quantitative monitoring and improvements based on user feedback.
