Worked on stabilizing the SD-Select component in the solid-design-system/solid repository, focusing on improving how programmatic value updates are handled in both single and multi-select modes. Addressed a bug that previously prevented external changes from synchronizing correctly after user interaction, ensuring that updates to the value property are now reliably recognized across Angular and React integrations. Utilized TypeScript and front end development skills to align the component’s behavior with framework writeValue semantics, enhancing data binding reliability. Collaborated with design-system maintainers to standardize external-change handling and prepared the value-watcher logic for future refactoring and cross-framework compatibility.
