Andrea focused on enhancing the Mistica Design System within the Telefonica/mistica-design repository by refining interactive tokens for hover and pressed states. Using TypeScript and applying principles from UI/UX design and front-end development, Andrea improved the visual feedback and consistency of interactive UI components. The work addressed design-to-development handoff challenges by making token behavior more predictable, which reduced UI discrepancies and established a stronger foundation for future token-driven updates. Although the scope was limited to a single feature over one month, the depth of the implementation contributed to a more reliable and maintainable design system for ongoing and future development needs.
