Mobile App Development (React Native)

Overview

I design and build cross-platform mobile applications using React Native, shipping to both iOS and Android from a single codebase. Whether you need a customer-facing app, an internal tool, or a complex platform with real-time features — I handle the full lifecycle from idea to deployment.

Every app I build is designed with real users in mind: fast, accessible, and reliable even under poor network conditions.

What You Get

• Full lifecycle ownership — from UX planning and wireframes to production release
• Responsive, pixel-perfect UI for all screen sizes (phones and tablets)
• Offline-first architecture with local storage and background sync where needed
• Secure authentication — JWT, OAuth, biometrics, OTP flows
• Role-based access control for multi-user apps (admin, manager, customer, etc.)
• Push notifications — local and remote via FCM / APNs
• Real-time features — chat, live updates via WebSockets or Firebase
• Clean navigation architecture — tab bars, drawers, deep links, modals

Tech Stack

Core

• React Native (Expo or bare workflow, depending on your needs)
• TypeScript for full type safety

State & Data

• React Query / TanStack Query for server state and caching
• Zustand or Redux Toolkit for complex local state
• MMKV / AsyncStorage for persistent local storage
• REST APIs or GraphQL — fully integrated with error handling and retry logic

Native Capabilities

• Camera, gallery, location, contacts, biometrics
• Payment integrations (Stripe, in-app purchases)
• HealthKit / Google Fit if needed
• Maps (Google Maps, Mapbox)

Testing & Quality

• ESLint + Prettier for code consistency
• Manual testing on real devices (iOS and Android)
• Expo Go / TestFlight for early previews

App Types I Build

• Business apps — field tools, CRM companions, inventory management
• Healthcare apps — patient portals, appointment booking, vitals tracking
• E-commerce apps — product listings, cart, checkout, order tracking
• Social / community apps — feeds, profiles, messaging
• Internal ops tools — dashboards, approvals, reporting
• Education apps — courses, quizzes, progress tracking

Design & UX

Good mobile apps don't just work — they feel natural. I pay close attention to:

• Platform-specific conventions (iOS vs. Android patterns)
• Gesture handling and smooth animations (Reanimated 2/3)
• Accessibility (screen reader support, proper font scaling)
• Loading states, error states, and empty states — every screen handled

Delivery & Deployment

Build Pipeline

• Expo EAS Build for managed workflow, or custom CI with Fastlane for bare projects
• Separate environments: development, staging, and production
• OTA (over-the-air) updates via Expo Updates where applicable

App Store & Play Store

• Full iOS App Store submission — bundle ID, provisioning profiles, certificates, App Store Connect setup, metadata, screenshots
• Full Google Play Store submission — signing keys, release tracks, Play Console setup, store listing
• Guidance through review requirements and content policy
• App icon, splash screen, and store screenshots prepared

Post-Launch

• Bug fix period after go-live
• Documentation for your team to manage OTA updates
• Handover of all credentials, certificates, and source code
