Myung worked on the LifeSG/react-design-system repository, delivering 22 features over seven months focused on accessibility, theming, and design-system consistency. They engineered token-based theming for color, font, shadow, and border-radius, enabling dynamic light/dark modes and brand-specific themes such as A11yPlayground, SupportGoWhere, IMDA, and SPF. Using React, TypeScript, and styled-components, Myung enhanced component accessibility with ARIA attributes, keyboard navigation, and semantic markup, while refactoring styling for visual coherence and maintainability. Their work included Storybook integration, comprehensive documentation, and responsive design improvements, resulting in a robust, scalable component library that improved developer onboarding, accessibility compliance, and UI consistency.

Aug 1, 2025Delivered key design-system improvements for August 2025 (LifeSG/react-design-system), focusing on shadow consistency, accessibility, and read-only form stability. Implemented a Shadow Token System Overhaul with token-based shadows across components, updated createShadow to support RGBA colors, and added type safety for shadow props, reducing styling drift and runtime errors. Enhanced Alert accessibility with ARIA attributes, focus management for collapsed content, and refactored styling for clearer visual hierarchy; documentation was updated with accessibility examples. Fixed read-only input and select padding to align left margins across input-related components, improving form consistency. These changes strengthen design-system consistency, accessibility compliance, and developer experience, enabling faster UI iteration with fewer regressions.
