React Native Mobile App Development | iOS & Android AppsM J
I design and develop fast, scalable, and beautifully crafted mobile apps using React Native—a powerful framework trusted by startups and enterprises alike. Whether you’re building a smart home controller, a real-time railway app, or a healthcare solution, I ensure seamless performance, offline capability, and App Store/Play Store readiness from a single codebase.
What's included
Cross-Platform Codebase
A fully responsive and maintainable mobile application built using React Native that works across iOS and Android from a single codebase.
Navigation & Routing Setup
Complete setup of in-app navigation using React Navigation (stack, tab, drawer), including deep linking, route guards, and custom transitions.
State Management
Predictable data flow using Redux Toolkit or Context API with hooks, persistent states, and middleware for asynchronous data handling.
Authentication Module
Integration of secure user authentication: email/password login, OTP, biometrics (Face ID/Touch ID), and optional social login (Google, Facebook).
Backend API Integration
Connection to your REST or GraphQL backend using Axios or Apollo. Includes error handling, loading indicators, retry logic, and secure token storage.
Push Notifications
Setup with Firebase Cloud Messaging (FCM) or OneSignal, including topic-based messages, in-app alerts, and background handling.
Offline Functionality (Optional)
Add caching, SQLite, or Realm support for data persistence and offline mode handling—great for unstable internet environments.
Performance Optimization
Efficient list rendering, lazy loading of assets, image caching, and reduced bundle sizes to keep the app fast and memory-efficient.
Store-Ready Build Exports
Final build deliverables including signed APKs, AABs, and iOS .ipa or archive builds ready for submission to App Store and Google Play.
OTA Updates + Testing Suite
Optional CodePush for over-the-air updates and a Jest/Detox-based testing framework for critical components and UI flows.
FAQs
Yes, using React Native I deliver a single codebase that supports both platforms, ensuring consistent UX and reduced maintenance.
Yes, I’ll prepare signed builds and provide guidance or direct support to get your app approved and live.
Absolutely. I work with both REST and GraphQL APIs and implement secure token handling, error flows, and loading states.
Yes, I can integrate Firebase Auth, Firestore, Storage, Analytics, as well as Twilio, Stripe, Mapbox, AWS, and more.
If needed, I can implement local caching or databases (AsyncStorage, SQLite) so your app works without internet.
I follow best practices for asset loading, memory usage, and layout rendering to ensure the app performs smoothly even on older devices.
Yes, I’ve built real-time features using WebSockets, SignalR, Firebase, and MQTT. Chat, tracking, alerts – no problem.
That’s up to you. I can match your Figma designs exactly or design a modern UI from scratch with your branding.
Yes, I can set up Jest for unit tests and Detox for UI/E2E tests depending on the level of coverage you require.
Yes, I offer post-launch maintenance, new feature additions, bug fixing, and version upgrades (including React Native upgrades).
