Worked on stabilizing the notification system within the LambdaIITH/Dashboard repository by addressing a backend issue involving hardcoded user IDs. Focused on backend development using Python, the solution replaced static identifiers with dynamic user context for Firebase Cloud Messaging token retrieval and notification access control. This approach improved both the security and reliability of notification delivery, ensuring that messages are sent only to authorized users and reducing the risk of misdelivery. The changes also enhanced maintainability by establishing a scalable pattern for notification logic, supporting future access control improvements. Skills applied included API development, backend development, and database management.
