Mobile App Developer | iOS & Android | AI Mobile App Development

Need a Flutter mobile app developer to turn your app idea into a real product? I help founders, startups, and businesses build production-ready iOS and Android apps with Flutter, backend/API integrations, OpenAI-powered features, subscriptions, and App Store / Google Play deployment. I’m a Top Rated Flutter developer with 100% Job Success, focused on building clean, scalable, and launch-ready mobile products. I’m not just here to “write code.” I can help you think through the product, define the MVP, choose the right technical approach, and build a first version that is simple, reliable, and ready for real users. 𝐖𝐡𝐚𝐭 𝐈 𝐜𝐚𝐧 𝐡𝐞𝐥𝐩 𝐲𝐨𝐮 𝐛𝐮𝐢𝐥𝐝 • Flutter iOS & Android apps • AI-powered mobile apps • MVPs for startups and non-technical founders • Education, productivity, wellness, coaching, and fitness apps • Subscription apps with RevenueCat • OpenAI / ChatGPT API integrations • Firebase, Laravel, REST API, and custom backend integrations • User authentication, onboarding, push notifications, and payments • App Store / TestFlight / Google Play deployment • Existing Flutter app fixes, redesigns, and rebuilds 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐏𝐫𝐨𝐜𝐞𝐬𝐬 • Understand your idea, users, and core features • Define a clear MVP scope, timeline, and milestones • Build the Flutter app with clean architecture • Integrate backend APIs, authentication, payments, AI, or subscriptions • Test the main user flows and fix issues before release • Prepare builds for TestFlight, App Store, and Google Play • Support improvements after launch 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤 • Mobile: Flutter, Dart • Backend & APIs: Laravel, PHP, REST APIs, MySQL • AI: OpenAI API, ChatGPT integration, AI app features • Cloud & Services: Firebase, Cloud Firestore, FCM, Supabase • Payments & Subscriptions: RevenueCat, in-app purchases, Stripe integrations • App Features: Authentication, push notifications, analytics, file uploads, maps, admin/API integration • Tools: Cursor, Claude, ChatGPT, Git, App Store Connect, Google Play Console 𝐑𝐞𝐜𝐞𝐧𝐭 𝐰𝐨𝐫𝐤 • Inivo: AI Study Planner — Flutter app with AI planning, subscriptions, authentication, and store release • Neurvora — mental performance app with Flutter, backend integration, subscriptions, and production launch • Trainer/athlete coaching MVP with mobile app, backend APIs, scheduling, and progress tracking • Existing Flutter app fixes, API integrations, and App Store / Google Play updates I also use AI tools like Cursor, ChatGPT, and Claude to move faster, but I don’t blindly ship AI-generated code. I review the code, test the flows, and keep the project maintainable. 𝐖𝐡𝐚𝐭 𝐲𝐨𝐮 𝐠𝐞𝐭 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐦𝐞 • Clean and maintainable Flutter code • Clear communication and regular progress updates • Practical MVP thinking without overcomplicating the build • Help with both development and launch decisions • App Store / Google Play release support • Long-term support for fixes, updates, and new features If you want the cheapest possible app, I’m probably not the right fit. But if you want someone who can help you build, fix, and launch a serious mobile product, send me your idea and I’ll give you honest feedback on the best way to build it.
