iOS, Android & React Native Engineer with 9+ years of experience, 100% Job Success Score, and $200K+ earned on Upwork. I build mobile apps that handle real users, real payments, and real scale not just demos. From marketplace platforms to field service apps to real-time messaging systems, I own the full stack: mobile UI through backend APIs through deployment. What I specialize in: • Marketplace & payment apps: Stripe, Razorpay, PayPal, escrow flows, webhooks, and failure handling • Field service & delivery apps: real-time tracking, route optimization, live agent monitoring (Mapbox, Google Maps) • Social & messaging platforms: secure real-time chat, scalable backend architecture • End-to-end mobile development: iOS (Swift, SwiftUI), Android (Kotlin, Java), React Native, Flutter • Backend APIs: Node.js, Python, REST APIs, third-party integrations, Firebase • Analytics & tracking: GA4, Facebook Pixel, in-app event tracking How I work: I think backend-first, so your app doesn't collapse at scale. I flag problems before they become costly, suggest improvements proactively, and write clean architecture not quick fixes you'll need to undo in 6 months. Who I work with: Startups building their first scalable product. Businesses adding payments, subscriptions, or analytics to existing apps. Teams that need a reliable full-stack mobile partner who can own both sides and keep things moving. If your app needs to handle payments, scale smoothly, and actually work in production, let's talk.

👋 Hi, I'm Maksym — a Flutter Developer and Mobile App Developer with 5+ years building cross-platform apps for startups and enterprises across Europe and the US. I'm a Flutter Developer who delivers Android, iOS, and Web from a single Dart codebase — faster delivery, lower cost, seamless experience on any smartphone. I work across the full mobile stack: UI/UX design, Flutter & FlutterFlow front-end, Firebase and backend integration, and App Store / Google Play publishing. As an AI Mobile App Developer, I think about the product, not just the code. Every architecture decision is driven by one question: will this still hold up when the app has 10× the users? 📱 RECENT WINS AS A FLUTTER DEVELOPER & MOBILE APP DEVELOPER 🔵 Movement AZ — Health & Fitness App As a Flutter Developer, I built an AI-powered Health & Fitness app with ChatGPT consultations, meal plans, rehab programs, and a built-in e-commerce shop.

Every choice is deliberate and built to scale. 🔄 MIGRATIONS & PLATFORM REBUILDS As a Flutter Mobile App Developer, I regularly handle platform migrations: • React Native to Flutter: smoother animations, faster load times, single Dart codebase • WordPress to Flutter App: synced CMS content, proper mobile UX, no workflow disruption • Laravel Web to Flutter Mobile: full feature parity, consistent design, lower maintenance cost One codebase. Two stores. Lower cost over the entire lifetime of the product. 🌐 FLUTTERFLOW DEVELOPER & FLUTTER FULL STACK DEVELOPER As a FlutterFlow Developer and Flutter Full Stack Developer, I bridge mobile front-end to powerful backends — Firebase Cloud Firestore, REST APIs, Node.js, Python, Google Cloud Platform.
