About

At my core, I am driven by an endless curiosity about how things work and how they can be made better. This mindset has taken me across the globe, giving me the incredible opportunity to live and work in five different countries. Along the way, I earned my Ph.D. in France, completed a Post-doc in Germany, and later broadened my business perspective with an Executive MBA from Germany's top business school. These diverse experiences have profoundly shaped my open-minded approach to problem-solving, teaching me to appreciate different cultures and perspectives both in life and in product development. Despite the academic background and leadership roles, I remain a deeply hands-on technologist and a pure early adopter. I love rolling up my sleeves and diving into new technologies—whether it's Generative AI, LLM integration, or the latest in mobile and automotive tech—to understand their true potential. Over the last 20 years, this passion has allowed me to bridge the gap between complex, deep engineering and intuitive, user-centric product execution. I've had the privilege of building and guiding cross-functional teams, reducing time-to-market, and shipping products that range from high-performance apps to advanced Software-Defined Vehicle solutions. Today, I am channeling this energy into building my next mobile venture, managing the full journey from a raw concept to launch. I am currently based in Germany and am actively connecting with pre-seed investors. Always open to a good conversation and new challenges, I am also available for Product Leadership roles, Strategic Technology Consulting, AI Solution Architecture, and freelance opportunities.
