Senior Product Designer with 12+ years of experience designing digital products, platforms, and marketplaces used by millions of users. I specialize in turning complex systems into clear, user-centered experiences across web and mobile. I’ve worked with global organizations including ING, ABN AMRO, Liberty Global, KLM, Kia Motors, and NEOM, helping teams design scalable products, data-heavy platforms, and enterprise tools. My work ranges from early product strategy and discovery to UX architecture, design systems, and high-fidelity prototyping. I’m comfortable working closely with founders, product teams, and engineers to shape product direction and ship real features. I also have a technical background and coding experience (Next.js, React basics, Python fundamentals), which helps me bridge the gap between design and development and move products forward faster. I thrive in complex environments—platforms, AI-driven products, marketplaces, and data-rich systems—where thoughtful product thinking and strong UX can make a real difference. Based in Spain, previously worked in Germany and the Netherlands (but I am also open to relocate). Available for product design, UX strategy, platform design, and design leadership engagements. 🚀…
