If you used tools like Cursor, Claude, Bolt, Lovable, Replit or v0 to speed up development and the app is now stuck at the “almost done” stage I can help you finish it and ship it. Many AI-assisted React Native projects run into the same blockers: unstable code patterns, production-only bugs, broken builds, store compliance issues, and performance that wasn’t optimized. 🏆I’m a React Native developer (Expo + RN CLI) building and stabilizing iOS & Android apps with TypeScript and a production mindset. My focus is turning a shaky MVP into a release-ready product you can safely maintain and scale especially for fast-moving startups (EU time zone). ⚙️ What I typically improve Clean up AI-generated code: structure, consistency, TypeScript hygiene, reliable state patterns Fix “works locally” problems: environment/config, build settings, permissions, native configs Resolve App Store / Google Play blockers: privacy, permissions, guideline compliance, release setup Performance: slow lists, unnecessary re-renders, navigation bottlenecks, memory spikes 🌍Integrations I work with often Backend: Supabase, Firebase Subscriptions: RevenueCat, Adapty, Superwall Analytics & attribution: AppsFlyer, Adjust, Tenjin, Meta SDK, TikTok SDK Push: OneSignal, Expo Notifications / FCM AI APIs: OpenAI, Whisper, Claude API Native features: camera, authentication, payments, deep linking 📱 Mobile Development Expertise: React Native (CLI & Expo) for cross-platform development Firebase (Authentication, Firestore, Cloud Messaging, Push Notifications) API Integration (RESTful APIs, GraphQL) App Testing, Debugging, and Optimization App Store & Google Play Deployment 💼 Industries I Work With: Crypto Apps E-commerce Apps Fitness & Health Tracking Education and Learning Platforms Social Media and Chat Apps Food Delivery and Booking Apps Utility and Productivity Tools 🚀 Why Choose Me: Dedicated developer with strong problem-solving skills Fast learner who adapts quickly to project requirements Clear communication and regular progress updates Focused on long-term collaboration and continuous improvement Passionate about writing clean, maintainable, and scalable code 📞Need a clean build from day one? I also develop apps from scratch with a scalable architecture and a single codebase for iOS/Android, ready for real users and store releases. 🔑 SEO for you my dear client 🙂 React Native, Expo, React Native CLI, TypeScript, iOS, Android, AI App Development, OpenAI, Supabase, Firebase, RevenueCat, OneSignal, AppsFlyer, Adjust, REST API, GraphQL, Performance Optimization, App Store, Google Play.
