Who brings us React Native projects

You want production-grade iOS and Android mobile apps without maintaining two distinct native codebases, or your current mobile app has fallen behind on React Native updates.

  • Companies with an established React or Next.js web application wanting a cohesive mobile experience for their users
  • Founders launching cross-platform mobile MVPs who need fast iteration without sacrificing native device capabilities
  • Engineering teams seeking cross platform react native developers to handle a complex upgrade or stabilize an existing app

Native iOS and Android performance from a single React codebase

As a cross-platform react native development company, we build and maintain native iOS and Android applications using Expo and React Native. Many teams reach out to hire react native developer talent when their existing React or Next.js web application needs a unified mobile presence. Operating as a dedicated expo app development agency, we help teams share business logic, design tokens, and API schemas between web and mobile platforms without sacrificing device-level performance. Our cross platform react native developers also provide an experienced react native upgrade service for older codebases requiring architectural stabilization, new architecture migrations, or SDK updates. AI coding agents accelerate implementation and regression test drafting, while senior engineers review every pull request and control production releases.

    • Expo Application Services (EAS) handling cloud compilation for iOS and Android
    • Over-the-air update channels distributing non-native bug fixes instantly
    • Apple App Store and Google Play Console distribution tracks and TestFlight builds
    • Crash reporting, error boundary logging, and real-time mobile performance telemetry
    • Push notification delivery pipelines via Apple APNs and Firebase Cloud Messaging

  • Your backend APIs and external services

    • Authenticated REST or GraphQL endpoints serving application business logic
    • Payment processing gateways handling in-app purchases and subscriptions securely
    • Identity providers managing OAuth sessions, refresh tokens, and staff access
    • Relational databases and object storage holding sensitive customer data off the device

Typical React Native requests

Typical scenarios we scope, not client case studies.

  • Extending a Next.js platform to iOS and Android

    A SaaS business has a web platform and needs companion mobile apps with push notifications and biometric login. We set up an Expo monorepo, share the existing TypeScript data schemas and API client, and deliver native mobile apps for both app stores.

  • React Native upgrade and technical stabilization

    A company has an older React Native application stuck on a deprecated SDK that fails recent app store submission rules. We audit dependencies, replace abandoned libraries, migrate to modern Expo EAS, and verify builds across target operating systems.

  • Dedicated cross-platform team for agency partners

    A digital agency needs white-label cross platform react native developers to deliver a mobile product for their client. We handle mobile architecture, UI implementation, and real-device testing under agreed milestone deliveries.

How a mobile project runs

  1. 01

    Architecture and scoping

    We evaluate your mobile roadmap, existing web services, required native device capabilities, and agree on the AI engineering package and technical scope.

  2. 02

    Mobile design and prototyping

    Designers craft platform-compliant interfaces and flow diagrams in Figma, ensuring smooth navigation and intuitive mobile interactions before development begins.

  3. 03

    Build, review and real-device testing

    AI coding tools implement modules under strict task scopes, engineers review every pull request for memory and security, and QA tests on physical devices.

  4. 04

    Store launch and release assurance

    We handle App Store and Play Store compliance, configure crash reporting and monitoring, hand over all source code and documentation, and support your launch.

How design, QA and operations connect

  • Platform-adapted mobile UX

    Designers ensure your application feels truly native on both platforms, honoring iOS conventions like swipe-back gestures and Android system navigation while preserving brand identity.

  • Real device QA and automated testing

    QA verifies critical flows like authentication, in-app purchases, and payment checkouts on physical iOS and Android hardware across multiple screen sizes and OS versions.

  • Controlled CI/CD and OTA releases

    Automated pipelines build release artifacts, run test suites, and manage staged rollouts through TestFlight and Play Console internal tracks, with rollback safeguards for OTA updates.

  • Long-term maintenance and SDK upgrades

    Routine updates for third-party libraries, React Native core, and yearly iOS and Android platform target requirements, backed by an agreed ongoing maintenance plan.

Not part of a React Native project

  • Browser-first marketing websites, desktop web dashboards, or headless web portals are scoped separately under Web Design & Development.
  • Developing fully separate native Swift or Kotlin codebases without React Native cross-platform code sharing is scoped under Native Mobile App Development.
  • Fixing broader multi-system legacy infrastructure outside the mobile codebase starts with an assessment under Application Modernization & Stabilization.
  • Stand-alone AI agent workflows or custom LLM integrations running outside the mobile application scope are delivered under AI Features & Agents.

FAQ

Frequently asked questions

Can we share code between our React web app and our React Native mobile app?

Yes. Business logic, state stores, custom hooks, API clients, and TypeScript data contracts can often be shared directly via a monorepo setup. User interface components must remain distinct because mobile uses native primitives like View and Text rather than web HTML tags. We architect shared packages so your team avoids writing business logic twice while preserving truly native app performance.

Why build with Expo instead of bare React Native?

Modern Expo eliminates fragile native build configuration while offering Expo Application Services (EAS) for automated cloud builds and over-the-air updates. With custom native config plugins and the Expo prebuild workflow, you retain full access to custom native iOS and Android code without managing brittle Xcode and Gradle projects manually. If your project specifically demands bare React Native, we support that too.

How does your React Native upgrade service handle legacy or broken apps?

Upgrades start with an architectural assessment of your existing dependencies, native bridges, and third-party packages. We identify deprecated libraries, configure compatibility layers, and update your React Native core incrementally. Automated tests catch regressions while engineers resolve breaking native API changes and verify core workflows on real devices before submitting updates.

Where is our code processed when AI tools are used?

It depends on the chosen delivery package. With Private / Local AI Engineering, open-weight models run exclusively inside client-controlled infrastructure or an agreed isolated environment. With Claude Code / OpenAI Codex Engineering, commercial coding tools process code under account settings and retention policies you approve. In both models, experienced engineers direct the work, review every change, and decide releases.
