Nestor Ruiz Medina
Senior Experience & Product Designer
I design complex products for institutions people rely on. Lately that means agentic AI: where it acts, where people stay in control, and what happens when it’s wrong. Trained as an architect. Now consulting: design strategy, leading teams, and still hands-on in the product.

About me
I own a product’s design end to end: research and strategy, the interface itself, and delivery alongside product and engineering. I go deepest on design systems and accessibility, and I set the standard for the teams I lead, including how we design with and for AI.
Originally from Spain, I trained as an architect but was always more interested in how people move through things than in the buildings themselves: the path more than the facade. That instinct is what turned into designing products, and it is still how I work.
