Summary
Product development is my calling — since 1999 I have been working at the intersection of technology, business, and innovation. With an interdisciplinary background in Applied Computer Science and Media Studies, and many years of experience in agile development, I turn complex requirements and problems into products and solutions. My approach is holistic: I connect business strategy, technical architecture, and user experience to maximize the chances of lasting product success.
My current focus is on the shift to the orchestration economy: agentic AI, local-first architectures, and data sovereignty. Since around 2020, I have been working intensively with AI and use it every day as an extension of my own capabilities.
I do not judge technologies by their hype, but by their potential to solve relevant problems. What sets me apart from pure nerds: I see the product, not just the code. What sets me apart from purely commercial product managers: I understand the technology deeply enough to judge what is possible and forward-looking — and what is not. My heart beats for innovation, problem-solving, and change.
