About this gig

Need a modern, premium native Android app built using Google's recommended technologies?

I am a senior mobile developer with over 7 years of native Android and cross-platform experience. I build apps that are clean, fast, and secure, using Kotlin and Jetpack Compose.

What I will build for you:

  • Modern UI layouts using Jetpack Compose and Material Design
  • Robust architectures (MVVM / Clean Architecture)
  • Offline-first capabilities using local SQLite databases (Room)
  • Background data synchronization modules for low-connectivity environments
  • API integrations (Retrofit, RESTful APIs, JSON)
  • Safe concurrency using Kotlin Coroutines and Flow
  • Firebase integration (Crashlytics, Analytics, Remote Config)
  • App Store publishing support

Why work with me?

  • Clean Code Guarantee: I use dependency injection (Hilt/Dagger) and write testable code.
  • Performance-Focused: I optimize startup times, memory usage, and keep APK sizes as small as possible.
  • Fiverr Delivery Standards: Clean Git history, clear documentation, and post-delivery assistance.

Every app is unique. Please reach out with your wireframes or requirements before placing an order to align on scope and delivery timelines.
