Hire React Native Developers — Cross-Platform Experts

React Native lets one developer ship production-quality iOS and Android apps from a shared codebase, typically cutting development cost by 40–60% versus maintaining two separate native projects. The JavaScript bridge has matured significantly — with Reanimated, Hermes, and the New Architecture, performance is near-native for most application types.

Standard placement is within 48 hours of contract signing. We maintain a bench of available React Native specialists at all times. For niche requirements (e.g., Bluetooth, AR, or payment terminal integrations), allow up to one week for matching.

We default to Expo for most projects because it dramatically simplifies the build and release pipeline. We use bare React Native when a project requires native modules not available in Expo, or when maximum control over native build configuration is needed. Both paths are well-supported by the Kultrix team.

Yes. We regularly join existing React Native projects to add features, fix performance issues, upgrade outdated dependencies, or migrate from Expo managed to bare workflow. We start with an audit of the current codebase and propose a prioritised action plan before writing new code.

Android is often the harder platform for React Native performance. Our developers enable the Hermes JavaScript engine, use Reanimated 3 for smooth animations on the UI thread, optimise list rendering with FlashList, reduce bridge crossings with the New Architecture (JSI), and profile with Flipper and systrace to find bottlenecks.

Yes. Our developers set up Fastlane for automated signing, build, and upload pipelines for both stores. They handle App Store Connect and Play Console configuration, prepare screenshots, write store listings, and guide you through the review process to minimise rejection risk.

Yes. We implement StoreKit 2 (iOS) and Google Play Billing (Android) using react-native-iap or RevenueCat as a cross-platform abstraction. We handle subscription logic, receipt validation, server-side entitlements, and restore purchases flows.

Zustand for global UI state and React Query for server state is our default combination — lightweight, TypeScript-friendly, and easy to test. For large enterprise apps with complex state machines, we use XState. Redux Toolkit remains a viable choice when the team already knows it well.

Offline support requires a deliberate architecture. We implement local-first data storage with WatermelonDB or MMKV, queue mutations when offline, sync on reconnect with conflict resolution, and surface connectivity state clearly in the UI. This is designed upfront, not bolted on later.

Yes. We write unit tests with Jest, component tests with React Native Testing Library, and end-to-end tests with Detox or Maestro for critical user flows. Test coverage is part of the definition of done on Kultrix engagements, not an optional extra.

We offer monthly retainer (fixed developer hours, guaranteed availability) and time-and-materials (billed weekly against tracked hours) models. Both include a dedicated account manager, transparent timesheets, and a structured weekly check-in. Minimum engagement is one month.

All Kultrix developers have a minimum of four years of professional React Native experience with shipped apps in both stores. They are assessed through technical interviews and practical take-home challenges before joining our bench. You will not receive a junior developer on your project.
