Yamasaka contributed to the giftee/design-system repository by developing and refining reusable front-end components, focusing on form grouping and layout flexibility. Over three months, Yamasaka built a Fieldset component supporting both horizontal and vertical layouts, implemented with React, TypeScript, and SCSS, and ensured accessibility through disabled state handling. The work included updating Storybook documentation, adding unit tests, and refactoring stories to improve build reliability and UX consistency. By centralizing icon management and enhancing component styling, Yamasaka improved design-system consistency and reduced development time for forms. The engineering approach demonstrated attention to maintainability, test coverage, and cross-application reusability.

June 2025: Implemented Fieldset component in giftee/design-system enabling horizontal/vertical layout options and a disabled state for contained controls, with Storybook examples and unit tests. Also fixed a Fieldset title type to resolve a type mismatch. This delivers a reusable, accessible form grouping pattern that speeds UI development and ensures design-system consistency across products.
