Hire React Native Developers for Expo and Bare Apps
RED SAG places dedicated React Native developers from our team in Tamil Nadu, India, with companies in the USA, UK, Australia, Canada and India. They build iOS and Android apps in TypeScript, work in your repository and Expo or EAS project, and join your stand-ups and chat like any other member of the team.
React Native makes most sense when your company already has React on the web, or wants to share validation, API clients and business rules between web and mobile. Much of the work we see is keeping an existing app healthy: upgrading React Native versions, moving to Expo and EAS Build, adopting the New Architecture, and fixing the native build problems that stall releases. We also take on complete apps as a React Native app development company in India: React Native app development services with a fixed scope, from first screens to store release, for teams that do not want to manage a developer day to day.
You can hire dedicated React Native developers full time, part time or hourly, or agree a fixed price for a defined app or upgrade. Every engagement can open with a one-week paid pilot, so you see real commits and a real test build before deciding on a monthly arrangement.
What our React Native developers build for you
Consumer apps with Expo
iOS and Android apps built with Expo and Expo Router, using EAS Build for signed binaries, EAS Submit for store uploads and EAS Update for over-the-air JavaScript fixes between releases.
Mobile companions to web products
Apps that share TypeScript types, API clients, Zod schemas and business logic with your React or Next.js web app, often in a monorepo managed with Turborepo or Nx.
Commerce and subscription apps
Catalogue, cart and checkout flows with Stripe or Razorpay, in-app purchases and subscriptions through RevenueCat, and analytics events wired up from day one.
Apps with native features
Camera, barcode scanning, background location, Bluetooth, biometrics and secure storage, using maintained libraries such as react-native-vision-camera, or custom native modules when needed.
Version upgrades and New Architecture
Stepping old apps up through React Native releases with the Upgrade Helper, enabling Fabric and TurboModules, replacing unmaintained libraries and fixing Gradle and Pod errors along the way.
Performance and stability work
Finding slow lists and janky animations with React Native DevTools and the profiler, moving to FlashList and Reanimated, and cutting crash rates using Sentry or Crashlytics reports.

Junior, mid-level or senior
Pick the level that matches the work. Many teams pair one senior developer with a junior or mid-level developer to keep costs down without losing review quality.
Junior
1–3 years
Implements screens and small features in TypeScript, with pull requests reviewed by a senior developer.
- Build screens from designs with the app's components and styles
- Connect screens to existing hooks and navigation routes
- Write component tests with React Native Testing Library
- Fix UI issues that appear on one platform but not the other
Mid-level
3–6 years
Delivers whole features across iOS and Android, including device APIs and release builds.
- Plan navigation, data fetching and state for a complete feature
- Integrate push notifications, payments, deep links and analytics
- Run EAS or Fastlane builds and manage testing tracks
- Investigate crash reports and fix platform-specific bugs
Senior
6+ years
Owns architecture, native integration and the release pipeline, and plans upgrades.
- Decide between Expo managed, prebuild and bare workflows for your needs
- Write or adapt native modules in Swift or Kotlin
- Lead React Native version upgrades and New Architecture adoption
- Set up CI, OTA update channels and a safe rollback process
Common React Native problems our developers avoid
Using OTA updates for native changes
EAS Update can only ship JavaScript and assets. Pushing an update that depends on a new native module crashes older binaries. Developers track runtime versions so updates only reach compatible builds.
Falling many versions behind
Skipping upgrades for a year turns a routine change into a painful project, and store SDK requirements eventually force it. We keep apps close to supported React Native and Expo SDK versions.
Heavy work on the JavaScript thread
Large lists in ScrollView and animations driven from JavaScript cause dropped frames. Our developers use FlashList, memoised row components and Reanimated worklets that run on the UI thread.
Secrets bundled into the app
Anything in the JavaScript bundle can be extracted from the binary. API secrets stay on your server, tokens go into the Keychain or Keystore through secure storage, never AsyncStorage.
Ways to hire
Four ways to work with our React Native developers, and when each one makes sense for React Native work.
Full-time dedicated developer
One developer works only on your product, around 160 hours a month, inside your tools and sprint rhythm.
Suits a mobile app that releases often and sits at the centre of your product, with features and platform work in every sprint.
Fixed monthly fee, invoiced monthly
Part-time dedicated developer
The same developer every week for about 80 hours a month, usually half days or agreed days.
A good match for a stable app that needs Expo SDK upgrades, store compliance changes and a modest feature backlog.
Fixed monthly fee for the agreed hours
Hourly
Pay only for tracked hours against tickets you raise. Hours and task notes are shared with every invoice.
The right choice if you need a React Native developer for hire on a short job: a broken iOS build, a store rejection, an OTA update gone wrong or an audit before a big release.
Tracked hours, invoiced monthly
Fixed-price project
A written scope, a fixed quote and milestones. We carry the estimate risk; changes are quoted before they are built.
Works for defined jobs such as an MVP from agreed screens, a version upgrade or moving a bare app onto Expo and EAS.
Milestone payments against an agreed scope
Indicative rates for React Native developers

How we vet and assign React Native developers
Technical interview
A senior engineer on our side interviews every developer on the stack you are hiring for, covering the topics listed on this page, before they are put forward to any client.
Review of real work
We read code the developer has written, from our own projects or their earlier work, looking at structure, naming, tests and how they handle errors, not just whether it runs.
Practical trial task
A short task in the same stack, done in a real repository and reviewed like a pull request. It shows how someone works, asks questions and writes up what they did.
Matched to your brief
We put forward the developer whose experience fits your product and time zone, share a short profile, and you interview them yourself before anything is signed.
What the React Native interview covers
- How the JavaScript and native sides communicate, and what the New Architecture changes
- Expo managed workflow versus prebuild and bare projects, and config plugins
- List performance, Reanimated and avoiding work on the JavaScript thread
- Navigation structure, deep links and authentication flows with Expo Router or React Navigation
- Release management: signing, runtime versions, EAS Update channels and store review
The trial task
Build a small Expo app in TypeScript: a tab layout with Expo Router, a FlashList feed from a mock API with caching through TanStack Query, a detail screen with a validated form, and one device feature such as notifications or the camera. We review the pull request and run a development build on both platforms.
How onboarding works
- 01
Call and NDA
A short call about your product, stack and team. We sign your NDA, or ours, before you share code, designs or business details.
- 02
Profile and interview
We share the profile of the developer we recommend and you interview them. A match usually takes about a week, depending on availability.
- 03
Contract and IP
The contract assigns all code and work product to you once invoices are paid, and sets out rates, hours, notice and confidentiality.
- 04
Access through your tools
You invite the developer to your GitHub or GitLab, Jira or Linear, and Slack or Teams. You control access and can revoke it at any time.
- 05
Updates you can rely on
A written update at the end of every working day, a weekly summary with hours, what shipped and what is blocked, and a demo when you want one.
The developer's first week
- Create development builds for iOS and Android and document any environment or signing issues
- Review the React Native and Expo SDK versions, native dependencies and OTA update setup
- Agree conventions for navigation, state, styling and tests with your team
- Ship one real ticket through code review and an internal test build
Working hours overlap
Our team is in India (IST, UTC+5:30). These are the overlap windows we plan around; the exact hours are agreed in the contract.
United Kingdom
Our normal day (9:00–18:00 IST) covers roughly 9:00 am to 12:30 pm in London in winter and 9:00 am to 1:30 pm in summer. A developer working 11:00–20:00 IST can cover until about 2:30 pm GMT.
USA and Canada (Eastern)
On a shifted schedule the developer is online for about 9:00 am to noon Eastern (New York, Toronto), enough for stand-up, reviews and questions. Work carries on overnight and is ready in your morning.
USA and Canada (Pacific)
For California or Vancouver we agree a fixed early window, typically 7:00–9:00 am Pacific, plus written hand-offs at the end of your day. We are open that overlap is shorter here.
Australia
India is 4.5 to 5.5 hours behind Sydney and Melbourne, so our normal day overlaps your afternoon, roughly 1:30–5:30 pm AEST. Perth overlaps from about 11:30 am onwards.
Try before you commit
Start with a one-week paid pilot
Before committing to a month, you can start with a one-week paid pilot. The developer works on a real ticket from your backlog, in your repository and tools, with the same daily updates as a normal engagement. At the end you decide whether to continue, change developer or stop. The pilot is billed at the hourly rate for the hours worked, and the code is yours.
Replacement if it is not a fit
If the developer is not the right fit, tell us and we will replace the developer at no extra charge. The new developer is briefed from the shared notes and tickets, and we overlap the hand-over where we can so you do not lose momentum.
Hiring React Native developers: questions
How much does it cost to hire a React Native developer?
Indicatively, a full-time dedicated React Native developer from RED SAG costs about $1,700–3,500 a month depending on seniority, and hourly work around $15–30 an hour. GBP, AUD, CAD and INR ranges are in the rates table above. We confirm your exact rate in writing before any work starts.
Do you use Expo or bare React Native?
We default to Expo with EAS for new apps because it simplifies builds, updates and upgrades, and it now supports custom native code through prebuild and config plugins. For existing bare apps we work as they are, and only suggest moving to Expo where it clearly reduces your maintenance.
Who owns the app store accounts and signing keys?
Your business should. We ask you to create the Apple Developer and Google Play Console accounts and the Expo organisation, then invite our developer. Listings, reviews, signing credentials and update channels stay under your control, and access can be removed at any time.
Will the developer handle app store submission?
Yes. They produce signed builds with EAS or Fastlane, upload them to TestFlight and Play testing tracks, help you complete privacy labels and the data-safety form, and deal with reviewer feedback. We plan releases around review times so a launch date is not put at risk.
Can the same developer work on our React web app?
Often, yes. Many React Native developers are comfortable in React for the web, and sharing types and API code between the two is common. If the web side is large, we may suggest pairing them with a dedicated React or Next.js developer instead.
How soon can a React Native developer start?
Usually within a week, depending on availability and how closely a developer's experience matches your setup, such as Expo versus bare or a particular native SDK. If the right person needs a little longer, we tell you so plainly rather than rushing a weaker match.
What if the developer is not a good fit?
Tell us, and we will replace the developer at no extra charge. The replacement is briefed from your tickets and shared notes so work continues. You can also start with the one-week paid pilot to check the fit before agreeing a monthly engagement.
