React Native Mobile Development

We build cross-platform mobile applications in React Native — a single TypeScript codebase that ships to both the App Store and Google Play, with the backend and real-time infrastructure behind it built to match.

What this includes

Cross-platform apps

iOS and Android from one React Native codebase, with the platform-specific work isolated where it genuinely differs instead of forked wholesale.

Real-time and social features

Authentication, messaging, feeds and notifications on Firebase — the feature set behind a social network we built and shipped to both stores.

Backend and API for mobile

Node.js and Express services designed for mobile constraints: small payloads, offline tolerance, and versioned endpoints so old app versions keep working.

Store submission

Build configuration, signing, store listings and the review cycle. Getting the app written is only part of getting the app published.

Numbers

  • 2app stores shipped to from one codebase
  • iOS + Androidseamless performance across both platforms
  • 9+years of TypeScript and React experience applied to mobile

Evidence

RememberMe is a secure, scalable social network built in React Native and Firebase, released on both the Google Play Store and the App Store, with cross-platform features maintained across iOS and Android.

Common questions

React Native or native Swift and Kotlin?
React Native when the product is mostly screens, data and real-time updates, and you would rather fund one codebase than two teams. Native when the product depends on hardware or platform APIs that React Native does not reach well.
Can you publish to the stores on our behalf?
Yes, with your developer accounts. We handle build configuration, signing, listings and the review cycle, including the rejections that come with it.
Do you build the backend too?
Yes — usually Node.js and Express, or Firebase where real-time synchronisation matters more than custom server logic.
