In September 2025, Susuperli contributed to the ant-design/ant-design repository by developing flexible theming and semantic styling for core UI components, focusing on the Empty and Spin components. Using React and TypeScript, Susuperli introduced unified classNames and styles props that support both object and function formats, enabling dynamic, type-safe customization aligned with design-system conventions. The work included comprehensive tests, improved demos, and updated documentation, enhancing maintainability and consistency across components. By expanding semantic theming slots and simplifying test structures, Susuperli addressed business needs for design-system consistency and easier customization, demonstrating depth in UI/UX design and front end development practices.
