My Standart Design Process
Mictosoft Fluent Design System
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.

Design System - Dintel

Design System - 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.
