Developed and delivered a customizable Navigation Bar Clock Widget for the th-ch/youtube-music repository, enhancing user experience by providing an immediate time reference within the application’s navigation interface. The feature was implemented as a plugin, supporting both 12-hour and 24-hour formats with optional seconds display, and was designed for future extensibility to accommodate additional time-related UI enhancements. The work demonstrated proficiency in Solid.js and TypeScript, with careful attention to frontend component design and plugin-based architecture. Throughout the development period, the focus remained on feature delivery and maintainability, resulting in a lightweight, configurable component that integrates seamlessly with existing systems.
