Build and maintain the native iOS and Android apps for Indonesia’s largest donation platform.

  • Ship features on Android native (Kotlin, Jetpack Compose) with Kotlin Multiplatform to share business logic across both platforms.
  • Own features end to end across both platforms: from API contract to release, so behavior stays consistent on iOS and Android.
  • Improve app performance, stability, and crash-free rate on payment and donation flows.
  • Write unit and snapshot tests around reducers and shared KMP modules to keep releases safe.
