During their recent projects, Tsang enhanced the user experience and maintainability of front-end features across two repositories. In vizhub-core/vzcode, Tsang refactored the color picker widget using JavaScript and TypeScript, introducing dynamic cursor positioning, a dedicated close button, and uppercase hex output, while also improving debugging through extensive console logging and build tooling stabilization with Vite. For wtg/shubble, Tsang focused on the About page, refining typography, visuals, and link styling with CSS and React, and resolving layout inconsistencies by updating class naming conventions. The work demonstrated a thoughtful approach to UI consistency, debugging visibility, and maintainable front-end architecture.
