Developed a scalable Notifications API for the wikimedia/apps-android-wikipedia repository, focusing on enhancing support for users with large wiki sets. The work involved refactoring the API by removing the notwikis parameter and implementing batching of requests in groups of 50, which addressed API limit errors and reduced latency. This approach aligned with the existing batch pattern used in markRead, promoting consistency and maintainability across the codebase. Utilizing Kotlin and Android development skills, the developer improved the user experience when accessing notifications and reduced API risk, laying a foundation for future scalability and more reliable API integration within the application.
