Dedicated React Native engineers
Hire React Native developers who ship one codebase to both app stores
Grape5 connects US companies with pre-vetted, India-based React Native developers who build and maintain one JavaScript codebase for iOS and Android. Each engineer is screened on list performance, native modules, and store releases by senior Grape5 engineers, dedicated to your app, and backed by a free replacement if the fit is wrong.
In short
Grape5 connects US companies with pre-vetted, India-based React Native developers who build and maintain one JavaScript codebase for iOS and Android.
Each engineer is screened on list performance, native modules, and store releases by senior Grape5 engineers, dedicated to your app, and backed by a free replacement if the fit is wrong.
When to hire React Native developers
- Your React web team needs to ship a mobile app to both the App Store and Play Store, and staffing separate iOS and Android teams is not realistic. A React Native engineer reuses your team's TypeScript and React skills across one shared codebase.
- Your app scrolls a long feed that stutters and drops frames. You need someone to profile the JS thread, cut needless re-renders, fix FlatList configuration, and move heavy lists to FlashList.
- You need a native capability the JavaScript ecosystem does not cover, like a Bluetooth device, a payment terminal SDK, or a custom camera pipeline. A React Native engineer writes the TurboModule or bridge in Swift and Kotlin.
- You have an aging bridge-based app to migrate to the New Architecture with Fabric and TurboModules, or you want to move from bare React Native to Expo with over-the-air updates through EAS.
How we vet React Native developers
Every engineer we put forward is screened by a senior Grape5 engineer before you meet them. For React Native developers, we look specifically at:
- List and render performance: whether they can read a dropped-frame trace, cut unnecessary re-renders with memoization, set keyExtractor and getItemLayout correctly, and know when FlatList is not enough and FlashList is the right call.
- Native module work: writing a TurboModule or legacy bridge in Swift, Kotlin, or Objective-C, passing types across JSI, and handling threading between the JS thread and the main UI thread without blocking either.
- 60fps interaction: Reanimated worklets that run on the UI thread, Gesture Handler for gestures, and avoiding bridge round-trips that cause jank during drags and screen transitions.
- Release reality: EAS or raw Xcode and Gradle builds, code signing and provisioning profiles, CocoaPods and Gradle failures, an over-the-air update strategy with Expo Updates, and getting through App Store and Play Store review.
- New Architecture and debugging: how Fabric, TurboModules, and bridgeless mode change a migration, how Hermes runs your JavaScript, and how to read a native crash in Sentry or Crashlytics down to the offending frame.

Frequently asked questions
Both. Grape5 screens for engineers who understand the tradeoff. Expo with EAS speeds up builds and over-the-air updates, while the bare workflow gives full control when you need custom native code or an SDK Expo does not support. Tell us your setup and we match someone who has shipped in it.
For most product apps, yes, once it is built well. The gaps show up in heavy lists, complex animations, and native-heavy features. That is exactly what we screen for: frame profiling, Reanimated on the UI thread, and knowing when to drop to a native module. If your app is graphics-intensive, we will tell you honestly.
A strong React Native engineer writes the native side themselves. We check that candidates can build a TurboModule or bridge in Swift and Kotlin, wire it into JavaScript through JSI, and handle threading. So a device SDK, a background task, or a custom camera feature does not stall your roadmap.
Your dedicated engineer does the build, code signing, provisioning, and store submission as part of the work. With at least 4 hours of daily overlap with US hours, you get live time for release reviews and TestFlight or internal-track testing, and the rest of the release grind runs while you are offline.
A typical start is 2 to 3 weeks, since Grape5 vets engineers before you meet them. Each one is dedicated to your app and managed and backed by Grape5. If the fit is wrong, you get a free replacement, so you are not stuck the way you would be with a freelancer who disappears.
