Everything you need to hire a great React Native developer — rates by region, must-have skills (including the New Architecture), interview questions, and the red flags that cost teams months of rework.
CEO, Ubikon Technologies
React Native is the most widely used cross-platform mobile framework in the JavaScript ecosystem. For teams already using React, it's the fastest path to a native mobile app. But "knows React" is not the same as "can build production React Native apps."
Here's what separates React Native developers who ship from those who struggle.
A React Native developer builds iOS and Android apps from a single JavaScript/TypeScript codebase. They're responsible for:
A senior React Native developer also:
| Region | Junior | Mid-level | Senior |
|---|---|---|---|
| USA / Canada | $80–$130/hr | $130–$190/hr | $185–$260/hr |
| UK / Western Europe | £55–£95/hr | £95–£150/hr | £145–£230/hr |
| Eastern Europe | $35–$60/hr | $55–$85/hr | $80–$130/hr |
| India | $18–$35/hr | $30–$55/hr | $50–$90/hr |
| Latin America | $28–$50/hr | $45–$75/hr | $70–$110/hr |
| Africa | $18–$32/hr | $28–$50/hr | $45–$75/hr |
Note: React Native developers often command a slight premium over Flutter developers in Western markets due to the larger existing JavaScript developer pool and JavaScript skill portability.

Look for apps on the App Store and Google Play. Check:
Walk through a project together:
Build a two-screen app: a list that fetches from a public API, handles loading/error/empty states, navigates to a detail screen. Use TypeScript.
What to look for:
any everywhere)map in a ScrollView)🚩 "I know React, React Native is basically the same" — It's not. Rendering model, layout engine, debugging tools, native modules — all different. This is the most common and most expensive misconception.
🚩 Only knows Expo managed workflow, never bare — Fine for side projects. Dangerous for production apps with custom hardware needs, specific native dependencies, or push notification configuration.
🚩 No TypeScript — "I prefer JavaScript" is acceptable in 2020. In 2026, a React Native developer who can't use TypeScript is a liability in any serious codebase.
🚩 Uses map() inside ScrollView for lists — A classic performance anti-pattern. Every item renders even if off-screen. Should be using FlatList.
🚩 Never deployed to both stores — App Store submission is a skill. If they've only published to one store, they've missed half the job.
🚩 Doesn't understand the JavaScript bridge — Or worse, doesn't know what JSI is. Any developer claiming to be senior must understand how JavaScript and native code communicate.
🚩 No offline handling — "The API is always up" is not a mobile app strategy. Mobile networks are unreliable. Good developers design for offline.
| Factor | React Native | Flutter |
|---|---|---|
| Language | JavaScript / TypeScript | Dart |
| Talent pool | Larger (JS ecosystem) | Smaller but growing |
| Performance | Good; improving with New Architecture | Faster rendering (Impeller engine) |
| UI consistency | Platform-native feel | Pixel-perfect, custom rendering |
| Web support | React Native Web (mature) | Flutter Web (stable) |
| Ecosystem | Huge npm ecosystem | Growing pub.dev |
| Learning curve | Low for JS/React teams | Moderate (new language) |
Our recommendation: React Native if your team is already JavaScript/React. Flutter for teams starting fresh who want the best cross-platform performance.
Best for: Single-developer MVPs, feature additions to an existing app
Risks: Availability, no QA, no backup developer, IP complications
Best for: 1–3 developer teams, steady delivery, PM included
Advantages: Agency handles staffing risk, code reviews included, replaceable if underperforming
Best for: Core product, long-term roadmap (3+ years), company-critical mobile app
