I build Flutter mobile apps with Firebase, Supabase, or a Node.js backend, including AI mobile apps that ship to the App Store and Google Play. Top Rated, 100% Job Success. One Flutter codebase. Mobile app development end to end. 🎨 Design Figma to Flutter, or I design it if you have none. Sketches become real Android and iOS screens. Incomplete design gets flagged before it burns weeks in development. 💻 Dev Flutter Mobile App Developer work: Android and iOS from one Dart codebase. Firebase, Supabase, or Node.js behind it. Installable builds, not “almost ready.” 🧪 Testing Real phones, before you see it. Crashes, slow screens, login, payments, push, and AI mobile app features. Bugs get fixed here, not after launch. 🚀 Deployment App Store and Google Play: signing, listings, privacy forms, review, resubmission. Live mobile app, not a zip file. You always know which step we are on, you get a build you can install, and you get a real date for the next one. No silence for weeks.

Flutter mobile app development from design to store, including takeovers when the last developer left. How I work Short call first. Written scope and milestones before code. If a date will slip, you hear it that week. I overlap US and UK mornings (PKT afternoon to night). Stack: Flutter, Dart, iOS, Android, Firebase, Supabase, Node.js, REST APIs, OpenAI API, Stripe, Google Maps, push notifications, Git. Send the idea, the Figma, or the repo. I will tell you the next step, a realistic timeline, and whether Flutter is the right call.
