I’m a Senior Android Engineer with over a decade of experience building and scaling consumer and enterprise apps (Mercado Libre, Disney/Globant, Hilti, Telecom/TV). I specialize in Kotlin + Jetpack Compose, MVVM/Clean architectures, and CI/CD to ship reliably at speed. Recent impact: refactors from fragments to Compose Navigation, reduction of crashes/ANRs, performance tuning, and Android TV experiences with Leanback + ExoPlayer. I enjoy leading initiatives, coaching peers, and partnering with backend/product to turn ideas into stable, measurable features.
Core: Kotlin, Compose, Hilt/Dagger, Coroutines/Flow, Retrofit/OkHttp, Room/SQLite, GraphQL, ExoPlayer, Play Console, Crashlytics/Bugsnag/New Relic, Bitrise/Jenkins, testing (JUnit/Robolectric/Mockito), accessibility.
