About this service

Summary

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.

Process

Discovery Call & Feature Breakdown Understand your app vision, user journeys, backend dependencies, and required integrations.

Project Setup Initiate the React Native project structure, install core packages, setup folder architecture, and configure CI scripts (if needed).

UI Implementation Build the frontend screens with responsive styling using Tailwind RN, Styled Components, or native styling solutions.

Authentication & User Flow Implement onboarding, login/signup, session handling, and access control based on user roles or states.

API Integration & State Management Connect to your backend and implement business logic. State management flows using Redux or Context are added here.

Feature Implementation Develop app-specific modules (maps, camera, BLE, calendar, payments, etc.) using native or community packages.

Notifications, Deep Linking & Offline Support Integrate push notifications, dynamic links, and offline features as per project scope.

Testing & QA Perform unit and UI testing with Jest and Detox. Manual device testing across iOS and Android phones/tablets.

Deployment Preparation Generate signed builds, set up environment variables, configure assets, app icons, splash screens, and metadata.

Final Delivery & Support Deliver builds, documentation, and offer support for publishing and post-launch updates.

FAQs

Will the app work on both Android and iOS?
Yes, using React Native I deliver a single codebase that supports both platforms, ensuring consistent UX and reduced maintenance.
Do you publish the app to the App Store and Play Store?
Yes, I’ll prepare signed builds and provide guidance or direct support to get your app approved and live.
Can you integrate my backend API?
Absolutely. I work with both REST and GraphQL APIs and implement secure token handling, error flows, and loading states.
Do you support Firebase or third-party tools?
Yes, I can integrate Firebase Auth, Firestore, Storage, Analytics, as well as Twilio, Stripe, Mapbox, AWS, and more.
Will the app support offline use?
If needed, I can implement local caching or databases (AsyncStorage, SQLite) so your app works without internet.
What about performance on low-end devices?
I follow best practices for asset loading, memory usage, and layout rendering to ensure the app performs smoothly even on older devices.
Can I request real-time features like chat or tracking?
Yes, I’ve built real-time features using WebSockets, SignalR, Firebase, and MQTT. Chat, tracking, alerts – no problem.
Is the UI going to be custom or based on a template?
That’s up to you. I can match your Figma designs exactly or design a modern UI from scratch with your branding.
Do you write tests?
Yes, I can set up Jest for unit tests and Detox for UI/E2E tests depending on the level of coverage you require.
Will you support future updates?
Yes, I offer post-launch maintenance, new feature additions, bug fixing, and version upgrades (including React Native upgrades).

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.
