React Native App Development

React Native lets you ship iOS and Android from one TypeScript codebase without giving up a native feel. I have used it in production since 2017, including the Paramount+ app for Amazon Fire TV and the Bitbrand mobile app. When the JavaScript layer is not enough, I write the native modules in Swift and Kotlin myself, so you are never blocked by a missing library.

What’s included

What you get

  • iOS & Android apps One TypeScript codebase, native navigation and platform polish.
  • Native modules Custom Swift and Kotlin bridges for BLE, camera, biometrics and more.
  • Code shared with web Business logic and design system shared with React or Next.js.
  • Expo & EAS Cloud builds, over-the-air updates and automated store releases.
  • Performance work New Architecture migration, startup time and list performance.
  • Store publishing App Store and Google Play releases, handled end to end.

Process

How it works

  1. 01

    Audit or scope

    For new apps, the first version; for existing ones, a code review.

  2. 02

    Foundation

    Navigation, state, CI/CD and builds on both platforms from week one.

  3. 03

    Features

    Iterative releases, tested on real iOS and Android devices.

  4. 04

    Launch

    Store submissions, crash monitoring and follow-up updates.

FAQ

Common questions

Something else? Ask me directly .

Is React Native still a good choice in 2026?

For most business apps that need iOS and Android, yes. The New Architecture removed the old performance bottlenecks, and it is used in production by Meta, Microsoft and Shopify. I compare it honestly with Flutter and native in my blog.

Will a React Native app feel native?

Yes, when it is built properly: it renders real native components, uses native navigation and follows each platform’s conventions. Where something needs to be truly native, I write that part in Swift or Kotlin.

Can you share code between our React web app and the mobile app?

Yes. With a monorepo you can share business logic, API clients, types and state, and increasingly UI too. I wrote a detailed guide on how I set this up.

Can you work on an existing React Native codebase?

Yes. I usually start with a short audit covering dependencies, architecture and performance, then agree a plan before changing anything.

Do you use Expo?

Usually, yes. Expo and EAS remove most of the build and release friction, and custom native code still fits in through development builds.
