Hire React Native Developers for iOS and Android

How to vet a React Native developer

Strong React Native developers are good React engineers who also understand mobile platforms. Look for solid TypeScript and React skills, experience shipping apps to both stores, familiarity with Expo and EAS, and the ability to write or debug native modules in Swift or Kotlin when a library does not cover a need. Developers who have never touched the native side tend to get stuck on build errors and platform-specific bugs.

Ask how they handled performance problems such as slow lists or heavy screens, how they upgraded React Native versions and whether they have worked with the New Architecture. Experience delivering fixes through over-the-air updates, and knowing when an update must go through the stores instead, is a good sign of production maturity.

• Strong TypeScript and React fundamentals.
• Shipped apps on both iOS and Android stores.
• Comfortable with Expo, EAS Build and EAS Update.
• Able to read and adjust native iOS and Android code.
• Has profiled and fixed real performance issues.

Interview questions we use for React Native developers

We test the combination of React knowledge and mobile awareness. Candidates walk through apps they have built, explain how they diagnosed problems and show they understand where JavaScript ends and the native platform begins. We also ask about release processes and store submissions they have managed.

Good answers name concrete tools, such as FlashList, Reanimated, Hermes profiling or the Xcode and Android Studio debuggers, and explain how they confirmed a fix worked on real devices. Candidates who have only used managed workflows suit many roles, provided they can learn the native side when a project needs it.

• How would you render a list of several thousand items smoothly?
• What changed with the New Architecture, and how does it affect native modules?
• How do you decide whether a fix can ship over the air or needs a store release?
• How do you handle deep links across iOS and Android, including when the app is closed?
• How would you write a native module for a feature no library supports?
• How do you keep animations smooth when the JavaScript thread is busy?

Onboarding a React Native developer in the first two weeks

In week one, the developer sets up the project locally with simulators and real devices, gets access to the repository, EAS or CI pipelines and crash reporting, and reads the navigation, state management and API patterns. They fix a few small bugs on both platforms, which quickly reveals how the build, review and release process works in practice.

In week two, they build a small feature end to end, including tests, and take it through a preview build for the product team. They also review dependency versions and upgrade status, since knowing how far the app is from the current React Native release shapes upcoming maintenance work. Our React Native app development page outlines the practices we follow on client projects, and the Flutter vs React Native comparison helps teams still deciding on a framework.
