Android Engineering Challenges
Eliminating ANR Crashes
Problem
Missing multithreading architecture and reliance on an older Android SDK caused the app to freeze and crash.
Solution
Re-architected with proper multithreading and bumped the SDK version, eliminating resource blocking.
Taming the MAUI Linker
Problem
.NET's aggressive linker stripped critical JSON deserialization code, crashing production Release builds.
Solution
Customized MSBuild pipelines with selective linker preservation directives.
Duplicate Notifications
Problem
As students changed classes, device tokens persisted in legacy Firebase groups, causing spam.
Solution
Designed a server handshake flow to tear down previous relationships server-side.
iOS-Specific Challenges
FCM Race Condition
Problem
Requesting an FCM token immediately after native APNs permissions consistently failed and returned null.
Solution
Built a resilient async polling mechanism to wait for the APNs backbone.
Native iOS Bindings
Problem
MAUI's linker over-optimized the payload, severing heavy native Firebase bindings.
Solution
Re-engineered iOS MSBuild definitions to disable linking on Firebase components and integrate static registrars.
15-Minute Build Times
Problem
iOS compiling took 900+ seconds per build due to Apple's mandatory LLVM optimizations and our hardware.
Resolution
Couldn't fix this natively, so we simply endured every 15-minute build cycle until the project shipped.
