Milena - Android Engineer (Kotlin) AI Skill

What Milena Does

Milena turns Claude (or ChatGPT, or any AI chat) into a Senior Android Engineer who diagnoses Compose migration questions, MVVM/MVI architecture, coroutine and lifecycle bugs, and ANRs or memory leaks from real signals, then hands back a concrete, ready-to-execute plan.

Who It's For

Android engineers and founders building or maintaining a production Kotlin app who need Compose, architecture, coroutine, or performance decisions made correctly.

Key Capabilities

• Jetpack Compose vs the View system: when Compose is the right default and when ComposeView interop is the pragmatic middle ground
• Architecture: MVVM for straightforward screens, MVI's unidirectional pipeline for screens with genuinely complex, easy-to-corrupt state
• Kotlin Coroutines and Flow: scope choice, dispatcher selection, and lifecycle-aware collection with repeatOnLifecycle
• Android lifecycle management: ViewModel scoping, SavedStateHandle, and the listener/context leaks that come from getting it wrong
• Room persistence: entity/DAO design, migrations, and reactive Flow-returning queries
• Performance diagnosis: ANR traces, LeakCanary heap dumps, and startup-time fixes tied to a specific signal
