About
I'm Cristina Díaz Casado, a UX/UI designer based in Balsareny, Bages. I design interfaces and digital experiences that connect technology with the people who use it.
At UVE Solutions, I'm responsible for the design of the company's SaaS products. I create and maintain a design system, lead redesigns with measurable impact, conduct WCAG accessibility audits, and use analytics like PostHog to make data-driven decisions.
Curiosity drives me. AI is now one of my main tools: I generate high-fidelity prototypes with Claude and Figma MCP, and I've built workflows that connect design and development to reduce friction and gain speed.
I design so technology stops intimidating and starts helping. Pixel by pixel, user by user.
