Specialist in Android application architecture — Google's recommended UI/domain/data layering + UDF, lifecycle & process-death survival (ViewModel/SavedStateHandle), Hilt DI, Room/DataStore/Paging data layer, WorkManager & foreground services, multi-module strategy (api/impl), UI-state & one-off-event modeling, and testing with fakes. Use for app structure, DI, persistence, and background-work decisions — not Compose UI or Gradle.

Specialist in Android app performance & diagnostics — app startup (cold/warm/hot, TTID/TTFD, App Startup lib), Baseline Profiles & Macrobenchmark, rendering/jank (frame budgets, slow/frozen frames, JankStats), ANRs (ApplicationExitInfo), memory (LeakCanary, LMK, onTrimMemory), Perfetto/Studio Profiler, Play Vitals thresholds that gate discoverability, app size, and battery (Doze/standby buckets/wake locks). Use for profiling and jank/startup/ANR/memory/battery diagnosis and regression gating.

Specialist in Gradle & the Android Gradle Plugin (AGP) — Kotlin DSL, version catalogs (libs.versions.toml), convention plugins (build-logic vs buildSrc), build performance (configuration cache, build cache, avoiding configuration-time work), KSP vs kapt, build types/flavors/variants, dependency management (implementation vs api, BOMs, constraints), R8/shrinking, and the AGP↔Gradle↔Kotlin↔JDK compatibility matrix. Use for build config, build speed, and dependency issues.

Specialist in Jetpack Compose UI architecture (Android) — composition/recomposition, stability & strong skipping, state hoisting & UDF, side-effect APIs, custom layout/Modifier.Node, lazy lists, type-safe Navigation-Compose, Compose performance (phases/deferred reads/compiler metrics), testing, and View interop. Use for Compose UI structure and recomposition/performance issues — not Material 3 tokens or general app architecture.

Specialist in Google Material Design 3 (M3 / Material You) — HCT/dynamic color, the md.ref/md.sys/md.comp token system, components, adaptive layout, tonal elevation, motion, and platform implementation (Jetpack Compose Material3, Material Web, Flutter). Use for M3 theming, token architecture, component/layout decisions, M2→M3 migration, and Material 3 Expressive.

Scaffold a new Android app with SDLC and Play-safe defaults — Kotlin/Compose Gradle project with version catalog, convention plugins, module layout, a targetSdk that meets the Play mandate, R8 on release, and git-ignored signing so it passes the pre-flight checker from day one. Use when starting a new Android project.

Set up Android app signing safely — generate an upload keystore, enroll in Play App Signing, and wire a Gradle release signingConfig that reads secrets from a git-ignored keystore.properties / CI (never committed). Use when configuring signing for a Play release.

Generate a GitHub Actions workflow for Android — JDK + Gradle caching, build, unit + instrumented tests, Android Lint, run the Android pre-flight checks, and (optionally) sign + upload a signed app bundle to a Play track. Use when setting up CI for an Android app.

Validated Google Play release — runs the pre-flight checks and clears the Play policy gates, builds a signed app bundle with a git-stamped versionCode, uploads to a track, and walks staged rollout (with halt/roll-forward). Use when releasing an Android app to Play.
