Worked on the mozilla/pontoon repository to enhance the notifications system by addressing a critical user experience issue related to unread state management. Using Redux and TypeScript, refactored the notification logic to eliminate the cap on visible notifications after marking all as read, ensuring the notification center accurately reflects read and unread statuses. The solution introduced a boolean unread flag and updated state management, resulting in more reliable notification counts and reducing user confusion. This work improved maintainability of the front end codebase and established a foundation for future features such as bulk actions and filtering, supporting ongoing scalability and usability improvements.
