Informazioni su questo servizio

Looking for a skilled Kotlin Multiplatform (KMP) developer to build your next mobile app? You're in the right place.


I'm a Senior Android Developer with 12+ years of experience, specializing in KMP to deliver shared codebases that run natively on Android and iOS without sacrificing performance or user experience.


What I can build for you:

  • Shared business logic (networking, data models, repositories)
  • Full Android + iOS apps with native UI using Compose Multiplatform
  • Clean architecture with MVVM and dependency injection
  • REST/GraphQL API integration


Why KMP over Flutter or React Native? KMP lets you share logic while keeping truly native UI on each platform. No compromises, no bridge overhead just clean Kotlin code your team can maintain long-term.


Why hire me?

  • Shipped Android apps at Redfin, Providence, Navan, and U-Haul
  • Cut CI build times by 50% and improved app startup by 10% at scale
  • I write clean, testable, documented code not throwaway freelance work
