Dario Ossa
@darioossa
I build reliable native Android features and improve mobile performance, releases, and offline experiences.
ChileWhat I'm looking for
I've delivered Android authentication, navigation, SSO, and business-critical product updates at Apply Digital, coordinating changes across three squads. I improved Android cold start by approximately 33–50%, resolved 30+ production crashes and performance issues, and strengthened release safety through Play Integrity-related work and R8/ProGuard validation.
Across native Android, iOS, Xamarin.Forms, and React Native products, I turn product needs into working UI, data, integration, testing, and release workflows. I build with Kotlin, Jetpack Compose, Coroutines/Flow, pragmatic MVVM and Clean Architecture, and recently delivered an Android-first Kotlin Multiplatform/Compose Multiplatform book-discovery app with shared architecture, tests, CI, offline persistence, and pagination.
