Full-Stack & Mobile App Developer | Flutter, React Native, Node.js
I'm a full stack and mobile app developer. I build the complete product: the iOS and Android app, the web dashboard, the backend and APIs, and the cloud setup it runs on. 8+ years, 100+ projects. One developer, one plan, nothing lost between teams. MOBILE APPS • Flutter / Dart for cross-platform iOS and Android apps that feel native • Native Swift, SwiftUI and Kotlin when a project needs camera, Bluetooth or deep OS access • React Native for teams already using it • Payments, in-app purchases, push notifications, maps, real-time chat • App Store and Google Play submission WEB AND BACKEND • Next.js, React and TypeScript for web apps, SaaS dashboards and admin panels • Node.js and Laravel for REST and GraphQL APIs, with PostgreSQL, MySQL, MongoDB or Firebase • n8n automations and third-party API integrations DESIGN AND CLOUD • Figma UI/UX design before any code • AWS, Google Cloud and DigitalOcean deployment, Docker, CI/CD RECENT RESULTS • Restaurant ordering app: A restaurant chain was losing money to third-party delivery fees. I built their own branded Flutter ordering app. Direct orders went up 27% in the first quarter. • Rescued React Native app: A startup's previous developer left with no documentation and half the features broken. I cleaned up the code, finished the app, and launched it on both stores in 3 weeks. • React Native to Flutter rebuild: The old app felt slow and users were leaving. I rebuilt it in Flutter, load times dropped by half, retention went up, and the client still works with me. HOW I WORK Six years ago my first Android app crashed on launch. I spent 14 hours fixing it and haven't missed a deadline since. You get a realistic timeline, daily updates during development, clean documented code, and an early heads-up if anything is at risk. I don't disappear halfway through. I'm not the cheapest developer here, but I treat your product like it matters, because to your users it does. Send me your idea. I read every one.
