Worked on refining interactive tokens within the Mistica Design System in the Telefonica/mistica-design repository, focusing on enhancing visual feedback and consistency for UI components. The approach centered on updating hover and pressed state tokens, which improved the clarity of user interactions and established more predictable component behavior. Leveraging TypeScript and front-end development skills, the work addressed design-to-development handoff challenges and reduced UI discrepancies. No major bugs were documented during this period, and the refinements laid a foundation for future token-driven iterations. The contribution emphasized UI/UX design principles, supporting a more cohesive and maintainable design system for ongoing development needs.
