I build production-ready Flutter and React Native apps for iOS and Android, and I specialize in one thing most developers avoid , cleaning up and scaling AI-generated codebases built with Lovable, Bolt, Cursor, or Claude Code. If your vibe-coded MVP works but needs a real developer to fix the bugs, restructure the code, and get it live on the App Store and Play Store , this is exactly what I do. What I regularly build: Secure authentication & role-based access Subscriptions, in-app purchases & payments Real-time features (chat, live updates, WebSockets) API-driven and data-intensive applications Clean, scalable architecture for long-term growth AI-generated MVP cleanup & production scaling I understand how AI tools generate code, where they cut corners, and how to turn an unstable MVP into a shippable product without rewriting everything from scratch. What clients can expect: Clean, maintainable code Honest timelines & daily/weekly progress updates Clear communication in plain English Smooth App Store & Play Store delivery Tech stack: Flutter, React Native, Firebase, Node.js, Laravel, REST APIs, databases, subscriptions, payments, and real-time systems.
