Worked on the bettercodepaul/swt2-bsa-frontend repository to enhance sidebar navigation by addressing active state highlighting issues across liga and ligatabelle routes. Focused on improving user experience and code maintainability, the developer refactored the sidebar component for greater readability and streamlined code paths. Adjustments to ligaID handling were implemented to ensure more accurate URL routing, reducing navigation-related support issues. The work included thorough lint cleanup, contributing to overall code quality. Utilizing Angular and TypeScript, the developer concentrated on front end development, delivering targeted UI improvements that reduced technical debt and stabilized routing behavior within the application during the month.
