Role	Required	Description
Android Developer		Uses Kotlin Coroutines and Flow at a basic level. Creates simple screens from design. Understands the application lifecycle.

Role	Required	Description
Android Developer		Independently implements complex screens with Kotlin Coroutines and Flow. Optimizes performance and memory consumption. Works with asynchronous patterns.

Role	Required	Description
Android Developer	Required	Designs mobile application architecture with Kotlin Coroutines and Flow. Optimizes performance for low-end devices. Implements CI/CD for mobile development. Mentors the team.

Role	Required	Description
Android Developer	Required	Establishes coroutine standards for the Android team: structured concurrency rules, choosing between StateFlow and SharedFlow for UI state, error handling patterns via CoroutineExceptionHandler. Implements coroutine testing via Turbine and TestDispatcher, defines cancellation and timeout rules, trains the team on advanced Flow operators.

Role	Required	Description
Android Developer	Required	Defines the Android platform's reactive programming strategy: architectural patterns for complex data pipelines (combine, zip, flatMapMerge), concurrency standards for multi-module applications, background task coordination protocols.
