During a two-month period, Tsang worked on front-end enhancements across the vizhub-core/vzcode and wtg/shubble repositories. In vzcode, Tsang refactored the color picker widget using React and TypeScript, introducing dynamic cursor positioning, a dedicated close button, and consistent uppercase hex output, while adding extensive console logging to improve debugging and state visibility. Tsang also stabilized Vite-based build tooling by resolving dependency update permissions and refining configuration for smoother development. In shubble, Tsang improved the About page’s UI and UX with refined CSS styling and class naming, addressing layout consistency and maintainability. The work demonstrated depth in debugging and front-end development.
