I’m Jesús Reyes, Senior UX Designer at PIX4D.
At PIX4Dcloud I’m part of the product decisions: I help define what we build, I design it and I measure if it works for users.
My background is in architecture, which gives me a structural way of thinking: products that scale and work as a whole. I’m now specializing in AI-ready design systems: a shared foundation that helps AI agents work consistently across every department of a company.
Approach
-
Behavioral Design & Data-Informed
I combine product data (KPIs, analytics) with behavioral psychology and mental models to understand why users do what they do. This allows me to design low-friction experiences that help people make better decisions, working for both the user and the business.
-
Product Strategy & End-to-End
I take projects from start to finish: problem definition, discovery, design, developer handoff and iteration with metrics. My goal is that what we design is usable, but also viable and scalable.
-
Design Systems & AI
I build and scale design systems with the same logic as an architectural plan: clear rules, reusable pieces and consistency. Right now I’m working on how to prepare these systems for products where people and AI agents work together.
Projects
-
How can we use technology to help people feel more empathy for animals?
-
How could we “bring back” the dead with today’s technology without losing who they were?
-
How can we redesign Madrid’s urban planning with strategies focused on a gender perspective?
-
How can we build an MVP that helps include all employees of a company, both on-site and remote, and avoids gaps and disconnection?
Writing
-
What a path in Athens teaches us about designing with AI.
-
AI agents now have a face. Muse, Dots and what Venturi taught us about ducks.
-
How to stop AI from filling our screens with “zombie interfaces”.
Lab
-
The improved text stays the same. Try three ways of seeing the change —direct replacement, highlighted text, and before and after— and compare which one lets you accept it.
-
Try three ways of waiting for an AI reply —skeleton, text shape, and checklist— and compare which wait feels shorter.
About me
Before designing digital products, I was an architect. For years I designed physical and urban spaces, and today I use the same way of thinking to build solid and consistent digital products.
I’m very interested in how technology changes our behavior. That’s why I’ve added Behavioral Design to the way I work. And because I believe digital products are moving towards ecosystems with AI agents, I’m training in Design Systems for AI.
I like learning, working in a team and, above all, challenges where strategy makes the difference.
