Ankush Singh focused on backend stability for the LambdaIITH/Dashboard repository, addressing a critical bug in the notification system. He removed hardcoded user IDs from the backend logic, ensuring that FCM token retrieval and notification access control now rely on dynamic user context. Using Python and leveraging skills in API development and database management, Ankush improved both the security and reliability of notification delivery. His work aligned notification authorization with authentication context, reducing misdelivery and unauthorized access. By establishing a maintainable backend pattern, he laid the foundation for future enhancements such as role-based access control and improved auditability within the system.
