I worked with Inigo at Freeletics, where he was the designer on my team. He combined a user-centric mindset with a strong ability to see the bigger picture and manage stakeholders effectively. His designs were modern, refined, and always a perfect fit for the platform.

I worked as a frontend developer with Iñigo at Cabify, where we collaborated as peers on the design system, bridging the web and mobile experiences. Our handoff sessions were always smooth and productive. We’d polish UX details together and make sure design and implementation stayed in sync.
