The full answer
React Native uses each platform's own native components for rendering, so apps feel native on iOS and Android while most of the code is shared. Creuto writes React Native in TypeScript, with the same linting, type checking and code review standards used on its web projects.
The biggest advantage is team economics. A product with a Next.js web app, a React Native mobile app and a NestJS API can be built and maintained by engineers who all work in TypeScript, which simplifies hiring and makes handover to an in-house team easier.
Creuto handles the parts that often trip up React Native projects: native module integration for payments, maps, camera and push notifications, performance tuning for long lists and animations, and upgrade paths as the framework evolves.
Where a feature needs platform-specific code, Creuto writes it in Swift or Kotlin and exposes it to the shared codebase. If an app's requirements are heavily native, Creuto will say so and recommend a native build instead.
Builds run through CI/CD pipelines that produce signed test versions for testers and store-ready releases. Creuto can publish to the App Store and Google Play and continue with support after launch.
