Hire Expo Developers — Managed React Native

Expo is a framework and set of tools built on top of React Native that handles the native layer configuration, build pipeline, and over-the-air update infrastructure. The managed workflow provides a curated set of native modules without requiring Xcode or Android Studio for most development tasks. This dramatically reduces the operational overhead of React Native development — faster onboarding, simpler CI/CD, and the ability to ship OTA updates without an app store review cycle.

Standard start time is 48 hours from contract signing. Expo developers are among our most available React Native profiles. For engagements requiring specific Expo SDK integrations — expo-camera, expo-sensors, or custom native modules — a two-to-three day matching window is typical.

The managed workflow lets Expo handle all native configuration — you write only JavaScript/TypeScript and Expo's Continuous Native Generation (CNG) produces the native projects automatically. The bare workflow exposes the native iOS and Android directories for full control, at the cost of managing native code yourself. Most new Expo projects should start managed and eject to bare only when a specific native requirement cannot be met with the Expo Modules API or community plugins.

EAS Build is Expo's cloud build service for creating native iOS (.ipa) and Android (.aab/.apk) binaries without requiring a Mac or a properly configured Xcode/Android Studio environment. Builds run on Expo's infrastructure, handle code signing automatically, and integrate with EAS Submit for one-command App Store and Google Play upload. It significantly simplifies the CI/CD setup for React Native applications.

Over-the-air updates allow you to ship JavaScript bundle changes to users without going through App Store or Google Play review. This is extremely valuable for critical bug fixes that cannot wait for a review cycle, minor UI improvements, and feature flag updates. OTA updates are limited to JavaScript layer changes — they cannot update native code, which still requires a full app store release. EAS Update provides channel-based rollout with rollback capability.

Yes. When the Expo SDK and community packages do not cover a requirement, we write custom native modules using the Expo Modules API — a modern Swift and Kotlin API that replaces the old React Native bridge approach. This covers native hardware integrations, platform-specific functionality, and performance-critical native code. We avoid the old bridge-based approach on new projects due to its deprecation in the New Architecture.

We implement push notifications using expo-notifications, which provides a unified API across iOS and Android. This covers device token registration, local and remote notification scheduling, notification categories and actions, foreground notification handling, and deep linking from notification taps. For high-volume production notification delivery, we configure the backend to use the Expo Push Notification service or direct APNs/FCM for maximum reliability.

Yes. Expo supports React Native for Web, allowing iOS, Android, and browser targets from a single codebase. This works well for utility applications where a native-feeling mobile app and a functional web experience are both needed. For web experiences where SEO, full accessibility, and rich browser functionality are priorities, we recommend a separate Next.js web application sharing a business logic package with the Expo app rather than a single universal codebase.

Expo SDK releases roughly twice a year with breaking changes and new features. Our developers follow the official upgrade guide, use the expo-doctor CLI to identify compatibility issues, update dependencies methodically, test on both platforms after each upgrade, and rebuild any custom native modules that are affected by API changes. We recommend staying within one SDK version of the latest release to avoid accumulated upgrade debt.

Yes. We write unit tests with Jest for business logic and custom hooks, component tests with React Native Testing Library for UI behaviour, and end-to-end tests with Maestro or Detox for critical user flows. EAS Build integrates test execution into the CI pipeline so tests run on every build before the binary is submitted to the stores.

Yes. Migrating from bare React Native to Expo managed workflow (or Expo with CNG) is a well-defined process. We audit the existing native modules, replace them with equivalent Expo SDK or community Expo plugins where available, write custom Expo plugins for any remaining native customisations, and convert the build pipeline to EAS. The result is reduced native maintenance burden and access to the Expo Update infrastructure.

Monthly retainer engagements offer a fixed weekly developer allocation with guaranteed availability — well-suited to ongoing Expo app development with regular releases. Time-and-materials engagements are billed weekly against tracked hours — better for defined scopes like a new app build or a migration project. Both options include weekly progress reports, transparent timesheets, and a dedicated account manager. Minimum engagement is one month.
