Design Leadership · Design Systems · Agentic Product Design
I have been designing digital products for over 20 years, combining user experience (UX), product design and close collaboration with product management and engineering. From clarifying requirements to delivering a usable application, I design hands-on, lead design teams and connect user needs with technical possibilities.
Making solutions tangible early matters to me. It lets us test assumptions, resolve open questions and make better-informed decisions before committing substantial development effort. Depending on the task, my contribution spans research and UX concepts, design systems and AI-assisted frontend implementation.
Good UX helps people accomplish their tasks and businesses achieve their goals. That is why I consider user needs, business value and feasibility together. This helps us make informed decisions about which solutions to develop and where the investment is worthwhile.
Complex applications do not have to feel complicated to use. I structure content, workflows and journeys so people can find relevant information and understand the next step. The interface reflects their task, existing knowledge and situation, making it easier to use and helping reduce uncertainty and errors.
I establish a reliable shared foundation for design and engineering. We decide where design rules, tokens and components are authoritatively defined based on the project’s needs. Figma, Storybook or other tools are used where they add value. When multiple tools are used, their content needs to stay in sync. The goal is reusable components in the actual frontend, reducing duplicate work and leaving more room for product logic, technical architecture and integrations.
I use AI selectively to make solutions tangible earlier and shorten the path from design to a working interface. This helps teams test new approaches faster, reduce development effort and bring products to market sooner. What matters is where AI delivers a real advantage in each project.
