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.
