Sound familiar?
- Your app crashes and reviews are slipping.
- Keeping separate iOS and Android teams is too slow and too expensive.
- Hiring a senior React Native developer full-time is taking months.
- Offshore hand-offs and time-zone gaps turn one-day fixes into week-long threads.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.

Hire US-based React Native developers to build, maintain, or upgrade iOS and Android applications with shared TypeScript code. The right scope depends on whether your app uses Expo, manually maintained native projects, or custom Swift and Kotlin modules. Typical work includes navigation, offline synchronization, push notifications, and resolving platform-specific failures that do not appear in JavaScript unit tests or simulator-only checks.
NextGen Coding Company provides senior engineers based entirely in the US, with no offshore subcontracting. They follow your working hours and attend your standups. For upgrades from React Native 0.76 or earlier, identify New Architecture compatibility issues across native dependencies before estimating tasks. An NDA and full IP assignment come before code access; a 15-minute call is the starting point.
Frequently asked questions
- Should we use Expo or maintain native React Native projects ourselves?
- Expo is useful when its SDK, development builds, and configuration plugins cover your native requirements. Manually maintained iOS and Android projects give direct control over native configuration but add maintenance work. Review background execution, hardware integrations, existing native code, and release policies. Expo development builds support more native functionality than Expo Go alone.
- What is involved in upgrading React Native to the New Architecture?
- React Native 0.76 enabled the New Architecture by default, making native dependency compatibility an important upgrade checkpoint. Audit libraries for Fabric and TurboModule support, review generated native changes, and test both platforms on physical devices. React Native Upgrade Helper can clarify version differences, but build validation and interaction testing remain essential.
- Can a React Native developer work on Swift and Kotlin modules?
- A role involving native modules should explicitly require Swift or Objective-C for iOS and Kotlin or Java for Android. React experience alone does not establish those skills. Discuss the module's threading, lifecycle, permissions, and data contract during interviews. For New Architecture projects, include Codegen and TurboModule requirements in the technical brief.
- How should we test and release a React Native app?
- Combine Jest and React Native Testing Library for component behavior with device-level flows in Maestro or Detox. Validate permissions, deep links, interrupted network requests, and background transitions on iOS and Android. EAS Build, EAS Submit, or Fastlane can support release workflows, depending on your setup. Store credentials and signing access need explicit ownership.
- What happens if the React Native engineer is not the right fit?
- If the fit is not right, NextGen Coding Company brings in a replacement with a proper hand-over. For a mobile project, that hand-over should explain native build steps, signing dependencies, release status, and unresolved platform bugs. Documenting those details helps the incoming engineer understand the codebase without relying on scattered chat messages.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
