Owned the design, implementation and unit tests of the Android push notification infrastructure, leveraging AI-assisted development with Claude to accelerate engineering workflows across FCM token lifecycle management, token refresh handling, backend synchronization, user-device mapping, and message routing for targeted push notification delivery across Android devices. Architected and developed a user-configurable, offline-first Push Notification Preferences module using Flows, Coroutines, Hilt, GraphQL, Jetpack Compose, Arrow for error handling and Clean Architecture with MVVM, implementing local caching with DataStore and time-based cache refresh strategies to reduce unnecessary network calls and improve app responsiveness. Engineered observability for push subscription processing serving 5M+ daily user interactions, building structured Datadog logging, business and operational metrics, error classification, and tracking for 50K+ token-generation failures, enabling faster RCA and reliability improvements. Analyzed functional requirements and translated business use cases into comprehensive functional test scenarios, implementing automated test cases to validate feature behavior, edge cases, and end-to-end workflows and ensure production readiness replacing backend calls with WireMock.
