Worked on the thingsboard-edge repository to enhance front-end maintainability and user experience using Angular and TypeScript. Focused on reorganizing and cleaning up public API exports for echarts-widget.models, improving accessibility and enabling easier reuse across modules without altering existing functionality. This refactoring laid the foundation for more maintainable code and streamlined onboarding for downstream developers. Additionally, addressed dashboard configuration usability by fixing a bug that caused pop-up elements to remain open in edit mode, ensuring mouse events only propagate when appropriate. These contributions improved dashboard interaction stability and overall UX, demonstrating attention to both code quality and end-user workflow.
