I build modern cross-platform mobile applications using React Native, Expo, and TypeScript, helping startups and businesses bring their ideas to life with fast, responsive, and native-like user experiences. Whether you're launching a new MVP, extending an existing SaaS platform, or transforming a web application into a mobile experience, I handle the entire development lifecycle from application architecture and UI implementation to backend integration, testing, and App Store deployment.
Every app is built with performance, maintainability, and scalability in mind, featuring reusable components, secure authentication, native device integrations, offline capabilities, and intuitive navigation that feels at home on both iOS and Android.

What's Included

Cross-Platform Mobile Application
A production-ready mobile application built with React Native, Expo, and TypeScript, delivering a native-like experience across iOS and Android from a single codebase.
Mobile UI & Navigation
Responsive mobile interfaces with reusable components, intuitive user flows, smooth navigation using Expo Router or React Navigation, and adaptive layouts for phones and tablets.
Backend & API Integration
Integration with REST APIs, GraphQL, Supabase, Firebase, Node.js backends, authentication providers, cloud storage, and third-party services to power your mobile application.
Authentication & User Management
Secure authentication using Clerk, Supabase Auth, or Firebase Authentication, compatible backends, biometric login, protected screens, user profiles, and role-based access.
Native Device Features
Integration with push notifications, camera, image picker, geolocation, maps, file uploads, biometric authentication, deep linking, secure local storage, and offline synchronization where required.
In-App Purchases & Subscriptions
Implementation of RevenueCat, Apple In-App Purchases, Google Play Billing, subscription management, premium features, and purchase restoration for subscription-based apps.
Performance & Offline Experience
Performance optimization through efficient rendering, lazy loading, asset optimization, local caching with SQLite or AsyncStorage, secure storage, and responsive interactions across devices.
Testing & Quality Assurance
Manual QA, device testing, unit testing, integration testing, accessibility validation, and cross-platform compatibility testing to ensure a reliable user experience before release.
App Store Deployment
Configuration of Expo Application Services (EAS), production builds, App Store Connect, Google Play Console, OTA updates, app signing, store metadata, and release support.
