React Native apps beyond basic CRUD

React Native apps that need more than a UI kit.

Background location, native device APIs and real-time updates are where cross-platform apps usually get stuck. When React Native can’t do something on its own, I write the native module in Kotlin and Swift and bridge it into your shared codebase.
