Mobile Engineer. Android, iOS, Flutter and React Native.

Galang Aji Susanto

Mobile Engineer with 7+ years of experience and 13 apps shipped to the App Store, Google Play and AppGallery. I have built production apps in all four major mobile stacks: native Android with Kotlin, native iOS with Swift, Flutter and React Native. That range is my strength: I can choose the right platform for a product, move a team between stacks, and bring the same standards everywhere, from clean architecture and SOLID principles to test coverage that lets a team release with confidence.
