Nestor Ruiz Medina
Senior Product Designer
I design digital products: consumer apps used by millions, and the tools that run complex operations inside large companies. Most of my current work is agentic AI. That means deciding what the AI does, what people keep control of, and what happens when it gets something wrong.

About me
I have designed products for large organisations since 2022. What I do depends on the engagement. It can run from discovery and research, through interaction and visual design, to working with engineers as the product gets built. I go deepest on design systems and accessibility. On recent projects I led design workstreams: the mobile app at NS&I, visual design at Wimbledon, product design at BP. That included reviewing the team’s work, mentoring colleagues, and setting how we design with and for AI.
I am from Spain and trained as an architect. Even then I was more interested in how people move through a building than in the building itself: the route more than the facade. That instinct is what turned into designing products, and it is still how I work.
