Senior Flutter engineer who built and scaled a cross-platform app from 0 to 600K+ downloads on iOS and Android. If you're building a mobile app — or scaling one that's already live — you get a developer who's actually done it, not someone learning on your budget. Most developers can build a screen. Far fewer have taken an app from zero to hundreds of thousands of users and kept it fast, stable, and reliable the entire way. That experience means fewer surprises for you: I already know where apps break at scale, so we avoid those problems instead of paying for them later. Apps I've built and scaled: A subscription delivery app (iOS & Android) I built and grew from 0 to 600K+ downloads — flexible subscriptions, in-app wallet, integrated payment gateways, and real-time order tracking. Result: a production app that handles real users and real money, daily. Its delivery-partner logistics app, used by 500+ drivers every day to manage routes, orders, and live status — proof I can build complete, multi-sided systems, not just a single app. Migrated a live healthcare app from native iOS/Android to Flutter with zero downtime — so the business kept running while the tech got better. Built real-time video consultation on Agora SDK for a regulated platform — complex, compliance-sensitive features done right. What this means for you: A new app built from scratch — clean, scalable, and ready for the App Store and Play Store An existing app made faster, more stable, and ready to grow The hard features handled: payments, subscriptions, push notifications, real-time/live tracking A smooth native-to-Flutter migration without disrupting your users One developer who owns the result end to end, so you're not stitching together freelancers How I work: Clear communication, predictable timelines, and updates you don't have to chase. I treat your app like a product I'm invested in — because stable, growing apps are how I've built my reputation. Top Rated, 100% Job Success. If you're serious about building or scaling a mobile app, send me a message with what you're working on. I'll reply with how I'd approach it — no obligation, just a clear plan.

I have shipped production apps on both the App Store and Google Play and I know the difference between code that works and code that lasts. Apps I have shipped include Zealthy (US healthcare, 10k+ downloads), EasyDispatch (ride-hailing), Fooda (food delivery), QuikyGo, and Invitation Card Maker. All live on App Store and Play Store. I am a full stack mobile developer — meaning I do not just build the app, I build the backend, the APIs, the database, and handle the App Store submission end to end. No handoffs, no "that is not my job," no waiting on three different freelancers to finish one feature. My stack: Flutter, FlutterFlow, React Native, Swift, and Kotlin on the frontend. Firebase, Supabase, Node.js, and REST APIs on the backend. I have built iOS and Android apps across healthcare, real time payments, location based services, and social platforms. What makes me different is that I think about the product, not just the task. Before writing a single line of code I ask the right questions, understand what you are trying to achieve, and make sure what I build actually solves the problem. Here is what I work with end to end: Mobile (Frontend): Flutter, FlutterFlow, React Native, Expo, Swift, Kotlin, Dart, native iOS, native Android Backend and Database: Firebase, Firestore, Supabase, Node.js, Express, REST APIs, GraphQL, PostgreSQL Features I build regularly: Stripe and in-app payment integration, real time chat and push notifications, GPS and Google Maps, video and voice calling with Agora, App Store and Play Store submission, WebView integrations, and native SDK bridging Deployment: iOS App Store submission, Google Play Store deployment, TestFlight, internal testing tracks, CI/CD setup I have worked with clients across healthcare, eCommerce, fintech, social media, and on-demand services. I am comfortable jumping into existing codebases, not just greenfield projects, and I take pride in leaving code cleaner than I found it. I respond quickly, communicate clearly, and deliver what I say I will deliver. If you have a mobile app project in mind, let us talk about it.

Top Rated Senior Flutter developer - 34 apps shipped, 1,700+ hours, 100% Job Success. I build and scale vacation rental, real estate, property/construction management, and GPS-based platforms - the kind that handle real money and real users, not just demos. A few things I've built: - A vacation-rental platform now managing 1,500+ active properties and $2M+ in monthly transactions - scaled to a $10M valuation in two years. - A real estate / construction management system handling multiple $2-3M projects for active daily users. - Real-time GPS tracking and geofencing apps where reliability isn't optional. What I can own for you, end to end: - Cross-platform apps (iOS + Android) from a single Flutter codebase - Backend & APIs - Node.js, MongoDB, Firebase, REST/GraphQL - Real-time features - live tracking, geofencing, maps, instant updates - Payments, bookings, multi-property/multi-tenant systems, dashboards - Chat, push notifications, auth, social login - the parts that usually break - App Store & Play Store launch, plus ongoing maintenance and new features What makes working with me different: I build the Flutter app AND the backend, so you get one senior developer who owns the whole product - no finger-pointing between freelancers, no half-finished handoffs. And you deal with me personally, every day. I stay hands-on in your code, backed by a 20-person team when you need to scale - but you never get passed off to a junior. How I work: Clear daily communication, realistic timelines, and clean, maintainable code your next developer (or in-house team) can pick up. I build with a modern AI-assisted workflow - faster delivery, lower cost, and the ability to add AI features like chat assistants or automation when your product calls for it. I'll also tell you honestly when a feature isn't worth the cost and point you to the faster path. That predictability is why most of my clients move from one project to an ongoing retainer. Recent clients have called me reliable, professional, and someone they "return to for future work" who "exceeded expectations." Whether you're launching a new product from scratch or scaling an existing app that's outgrown its original build - in rental, real estate, location-based tech, or any serious app - tell me what you're working on and I'll tell you honestly how I'd approach it.
