About Me
I'm a product designer based in sunny Alicante, Spain.
WHO AM I?
Since 2012, I've enjoyed turning complex problems into
simple, beautiful and intuitive designs.
When I'm not pushing pixels, you'll find me cooking,
gardening or working out in the park.

ENTER AD
2017 – 2021
UX / UI Designer at Critix Media LLC, Alicante
My mission in this company was to take projects from start to finish. The final clients were public institutions such as Murcia Turism Madrid Digital Costa Blanca Org.
Dev Express
I have worked on implementing a Fluent UI-based interface for Blazor applications, focusing on delivering a consistent, accessible, and modern user experience. While others have developed similar solutions using DevExpress, my approach has been to build on the design principles of Fluent, ensuring clean visual integration and a cohesive user experience across all components.
Bank Santander & Fintech Open Bank
I have extensive experience building and scaling design systems, including working with platforms like Openbank's Kubit and Flame. I'm skilled in using design tokens, variables, and structured JSON formats to ensure consistency across both design and code.
In Figma, I maintain a single source of truth where every component state and variation is fully documented, using tools like Tokens Studio. I also work closely with developers through Storybook to align implementation with design specs.
The same structure has been implemented in cooperation projects I've worked on with Amazon Zinia and Banco Santander. You can find the project link below.
DSL - Dintel
Institutional analysis for the Dintel Design System
As a UI/UX Designer, I took part in analyzing digital products from most public institutions in Spain. This work was key to defining the strategy and foundations of the Dintel Design System, aimed at unifying and improving the digital experience across public administration.
DSL - MUFACE
MUFACE (Mutualidad General de Funcionarios Civiles del Estado) is a public institution that provides healthcare and social benefits to Spanish civil servants. Its digital platform serves thousands of users, including public employees and administrative staff across Spain.
As part of the digital modernization effort, we developed a unified Design System to bring consistency, accessibility, and efficiency to their digital services. This system streamlined the design and development process, reduced duplication of efforts, and laid the foundation for a more user-centered experience across all touchpoints.
DSL - SEPE.ES
SEPE (Servicio Público de Empleo Estatal) is the Spanish national employment platform, serving millions of users across Spain.
As part of a major digital transformation, I led a heuristic evaluation and conducted card sorting exercises to identify usability and accessibility pain points across the portal. My focus was on extreme accessibility use cases to ensure the platform could serve all users effectively.
I mapped user journeys, detected critical issues, and collaborated with stakeholders to propose a full redesign of Spain’s largest public digital service — improving structure, navigation, and compliance with WCAG 2.1 AA standards.
