He built our iOS and Android app faster than we expected, kept us updated the whole way, and it has not crashed once since launch. He owned the entire build, the app, the backend, and the payment system, so we never had to juggle multiple freelancers. He is the first developer we actually trust, and we have already booked him for our next two projects. ❞ Marcus Bennett, Founder, NorthLoop Fitness You can get a similar result for your project , just click on Message and send a quick text to get started! I build Flutter and React Native mobile apps for startup founders who need a product that holds up once real users show up. I have shipped mobile apps to the App Store and Google Play across fintech, health, social, and productivity, and I own the whole thing: the app, the backend, and the API that ties them together. You will not need to hire three separate people to launch one mobile app. Here is why founders keep working with me: ✅ I ship the app and the backend, so there are no handoff gaps and no "that is not my part" moments. ✅ I build for iOS and Android from one clean Flutter or React Native codebase, which means faster delivery and a lower bill for you. ✅ I handle Firebase, Stripe, and subscription logic properly, not as a rushed afterthought bolted on at the end. ✅ I move at startup speed and have taken MVPs from idea to App Store and Google Play submission in a matter of weeks. ✅ I keep you in the loop with clear, regular updates, so you always know exactly where your project stands. ✅ I write production-ready code from the start, built to scale with you instead of being thrown away in six months. Who I help and what you can expect: I work with early and growth-stage startup founders, mostly US-based, who want to launch or scale a mobile app without the usual chaos. Most clients go from idea to a stable, investor-ready MVP in four to eight weeks. I spend the large majority of my time on Flutter and React Native app development, backend and API work with Node.js and Firebase, and payment and subscription integration with Stripe and in-app purchases. Ready to get your mobile app built right? 📩 Send me a direct message or invite me to your job here on Upwork. I will review your project and reply within 24 hours with an honest read on scope, timeline, and the best way forward. A few numbers that matter: 🔁 Most of my clients come back for a second project or refer another founder 🐛 Zero-crash launches, my apps ship stable and stay stable 💳 Stripe and subscription systems integrated cleanly on real production apps ⭐ 5-star reviews across every completed contract What I focus on most: 📱 Flutter app development for iOS and Android from a single codebase 📱 React Native app development for cross-platform mobile apps 🔌 Backend and API architecture, integration, and REST API development 💳 Stripe, in-app purchase, and subscription system setup 🔥 Firebase and Supabase backend configuration 🚀 MVP development for startups and founders 🛠️ App Store and Google Play submission and deployment 🐛 Crash fixes, performance tuning, and ongoing mobile app maintenance Tools and platforms I work with: Flutter, Dart, React Native, TypeScript, JavaScript, Firebase, Supabase, Node.js, Stripe, REST APIs, Git and GitHub, TestFlight, Google Play Console, and App Store Connect.

With nearly 4 years of software development experience, I architect and implement full-stack solutions across mobile, desktop, and web using modern declarative UI frameworks - primarily Compose Multiplatform and Flutter. My tech stack leverages Kotlin Multiplatform Mobile (KMM) for sharing business logic and data layers across platforms, while maintaining native performance and platform-specific optimizations where needed. My engineering approach emphasizes clean architecture principles with domain-driven design, leveraging MVVM and unidirectional data flow patterns. Core implementations include platform-agnostic state management, dependency injection via Koin/Hilt, reactive programming with Kotlin Flow/Coroutines, and comprehensive unit/integration testing. UI implementations strictly follow Material Design 3 specs with full WCAG 2.1 AA compliance. I've delivered enterprise-scale solutions for clients including Google and WSAudiology, working within their CI/CD pipelines and meeting strict performance, security, and reliability SLAs. Happy to deep dive into architecture decisions, tech stack choices, or platform-specific optimizations.
