React Native Developer | Mobile App Developer | iOS & Android Apps

Need a React Native Developer or Mobile App Developer who can take your idea from the first build all the way to a production-ready iOS & Android App? I’m a Top Rated Plus React Native Developer with a 100% Job Success Score, $50K+ earned, and 1,100+ hours on Upwork. I build and launch mobile applications for startups, growing businesses, and established products, with a focus on clean architecture, reliable performance, and code that can actually support the product after launch. I work across the complete mobile development lifecycle, so you are not hiring someone just to build a few screens. As your Mobile App Developer, I can handle the React Native frontend, backend integration, APIs, authentication, payments, notifications, maps, testing, App Store submission, Google Play launch, and the technical decisions that come with taking a real product to market.

My Upwork history includes long-term iOS/mobile development, React Native and Firebase work, Expo/Xcode support, and cross-platform application development. 𝐌𝐲 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐬𝐭𝐚𝐜𝐤 Mobile: React Native, Expo, TypeScript, JavaScript, iOS Development, Android App Development, Swift, Kotlin Backend & APIs: Node.js, REST API, API Integration, Python, Firebase, Supabase, PostgreSQL, MongoDB Mobile features: Push Notifications, Authentication, Social Login, Payments, Subscriptions, Maps, GPS, Camera Integration, Real-Time Chat, Analytics Deployment: App Store Connect, Google Play Console, TestFlight, Xcode, Android Studio, CI/CD Supporting technology: Flutter and Dart where the project genuinely calls for them What matters to me is not just whether the app works on my machine. It needs to work for your users, pass store review, remain maintainable, and give you a solid foundation for future features. When we work together, I start by understanding what you are building and why. Then I help define the right architecture, break the work into clear milestones, and give you working builds as development progresses. You will always know what is completed, what is next, and where the project stands. I also prefer to raise technical concerns early. If there is a simpler way to build something, a feature that will create unnecessary cost, or an architectural decision that may cause problems later, I will tell you before it turns into expensive rework. As a React Native Developer and Mobile App Developer, my goal is to give you a reliable iOS & Android App that is ready for real users, not just a prototype that looks finished. Send me a message or invite me to your project if you need a React Native Developer, Mobile App Developer, or iOS & Android App specialist who can take ownership from development through launch.
