ANDROID ENGINEERING CHALLENGES
SOLVED
ELIMINATING ANR CRASHES
PROBLEM: Missing multithreading architecture and reliance on older Android SDK 12.0 caused the app to freeze and crash.
SOLUTION: Re-architected with proper multithreading and bumped SDK version, eliminating resource blocking.
SOLVED
TAMING THE MAUI LINKER
PROBLEM: .NET 10 aggressive linker stripped critical JSON deserialization code, crashing production Release builds.
SOLUTION: Customized .csproj MSBuild pipelines with selective linker preservation directives.
SOLVED
DUPLICATE NOTIFICATIONS
PROBLEM: As students changed classes, device tokens persisted in legacy Firebase groups causing spam.
SOLUTION: Designed a robust server handshake flow in FcmService to tear down previous relationships server-side.
IOS-SPECIFIC CHALLENGES 🍎
SOLVED
FCM RACE CONDITION
PROBLEM: Requesting an FCM token immediately after native APNs permissions consistently failed and returned null.
SOLUTION: Designed a resilient asynchronous polling mechanism with Task.Delay to wait for the APNs backbone.
SOLVED
NATIVE IOS BINDINGS
PROBLEM: MAUI's linker over-optimized the payload, severing heavy native Objective-C/Swift Firebase bindings.
SOLUTION: Re-engineered iOS MSBuild definitions to disable linking on Firebase components and integrate static registrars.
ENDURED
15-MINUTE BUILD TIMES
PROBLEM: iOS compiling took 900+ seconds per build due to Apple's mandatory LLVM optimizations and outdated hardware restrictions.
RESOLUTION: We ultimately couldn't fix this natively due to hardware limitations. We were simply forced to endure and patiently wait through every agonizing 15-minute build cycle to finish the project!
