Overview

Owned mobile engineering at Telecrm, building and shipping critical features across Android and iOS platforms while solving complex platform-specific challenges.

Key Features

• Push Notifications: Added Android and iOS push notification capabilities, improving user engagement and real-time communication.
• iOS Deeplinks: Implemented deeplinks so that routing to URLs opens the iOS application directly.
• Click-to-Call Enhancement: Improved web-to-mobile click-to-call via a new native websocket layer. Previously required the app to be open — solved with native websockets that work in the background.
• Virtual Scrolling: Introduced virtual scrolls on all paginated views, solving exponential memory consumption from DOM element accumulation that caused severe performance degradation.
• State Restoration (Android 14+): Solved LMDK daemon issues where Android 14+ would kill the app when navigating to external services (camera, WhatsApp, calling). Built a state restoration service, in-app camera, and system-wide custom back button to maintain state.
• Notch Fixes: Fixed display issues from Android 14+ and iOS notch devices.
• ANR Resolution: Fixed Application Not Responding issues caused by excessive main thread activity by properly utilizing background threads.
• Capacitor Migration: Upgraded Capacitor from v5 to v7 for better platform support.
• Web Push Notifications: Improved reliability of web push notifications.

Key Bug Fixes

• Android LMDK Issues: App depended on external services which, when navigated to on Android 14+, would cause premature app kills and restarts from the beginning instead of the previous state.
• ANR Issues: The Android app was repeatedly triggering ANRs because too much activity was happening on the main thread.
• Notch Display Issues: Fixed layout and display issues on devices with notches across both platforms.

Technologies Used

• Angular / Capacitor: Cross-platform mobile framework
• WebSockets / Native WebSockets: Real-time mobile communication
• Android SDK: Platform-specific features
• iOS SDK: Deeplinks and push notifications
• Sentry: Error tracking and monitoring

Impact

• Improved app stability and user experience across Android and iOS
• Resolved critical crashes affecting Android 14+ users
• Enhanced real-time communication capabilities
• Improved scrolling performance on paginated views
