I’m Guillermo Sánchez, a Product Designer with 8 years of experience in design systems, UX, and new technologies for clients such as Prezero, Cepsa, Ferrovial, and Engie.

During my eight years of experience in digital product design and user experience (UX/UI), I have specialized in scaling design in complex environments, applying user-centered design, design systems, and UX strategy.

I enjoy working in multidisciplinary and cross-functional teams, collaborating closely with business, developers, technology, product owners, and other stakeholders.

I have created international strategic solutions in design and digital products for companies such as Prezero, Cepsa, Ferrovial, and Engie, applying agile methodologies (Scrum, Lean UX).

I am fascinated by how the best design is invisible, which is why I am highly experienced with UX research techniques such as customer journeys, user interviews, surveys, usability testing, and A/B testing, always measuring impact through metrics and KPIs.

In my projects, I combine UI design, interaction design, prototyping in Figma, and wireframes, with a strong focus on accessibility, responsive design, and visual consistency. I apply user-centered design methodologies from research and ideation to prototyping, usability testing, iteration, and final implementation.
