Xavi Marín

Senior Product Designer

Based in Barcelona, currently working at Uxia.

I’m a Senior Product Designer who builds, not just designs. I combine product thinking, UX/UI, and design systems with AI and code to take ideas from concept to production.

I use AI to accelerate the build process, ship features, create PRs, and iterate with engineering — closing the gap between designing a product and actually building it.
