Hire the Best Xamarin Developers

🏗️ Most developers build mobile apps. I build mobile products that survive version 2. Top Rated · $90K+ Earned · 100% Job Success · 7+ Years Experience There's a difference between an app that launches and an app that lasts. After 7+ years and 50+ production apps — built for startups shipping their first product and enterprises modernizing legacy Xamarin codebases — I know exactly what separates the two: architecture decisions made on day one. I specialize in .NET MAUI for cross-platform iOS & Android, with deep roots in Flutter, Xamarin, and ASP.NET Core backend. Whether you're starting fresh or inheriting a mess, I'll tell you the truth about what it takes — then build it. WHY CLIENTS CHOOSE ME ✅ Cross-platform apps that feel native — without the native price tag ✅ Clean MVVM + Dependency Injection architecture you won't rewrite in 12 months ✅ CI/CD pipelines, automated testing, and App Store deployment handled end-to-end ✅ Clear communication, regular updates, zero ghosting ✅ Long-term thinking — I build for your product's future, not just the current sprint WHAT I BUILD 📱 Mobile Apps (iOS & Android) → .NET MAUI with Shell navigation, MVVM, CommunityToolkit & Dependency Injection → Flutter with Dart, Provider / Riverpod / Bloc, and native integrations → Pixel-perfect responsive UI, 60fps animations, platform-specific optimizations → Offline-first architecture with local SQLite / Realm databases 🔄 Xamarin → .NET MAUI Migrations → Full codebase audit, renderer → handler migration, performance benchmarking → Upgraded to modern .NET 8/9 with Hot Reload and improved startup time → Custom controls rewritten with the new MAUI Graphics API ⚙️ Backend & Cloud → ASP.NET Core REST APIs with JWT auth, rate limiting & Swagger docs → Azure (App Service, Functions, Blob Storage, Notification Hubs, AD B2C) → Firebase (Auth, Firestore, Realtime DB, FCM push notifications) → Real-time features with SignalR — chat, live dashboards, instant notifications → GraphQL APIs and third-party integrations (Stripe, Twilio, Google Maps, SendGrid) 🤖 AI-Powered Features → On-device OCR with ML Kit & Tesseract → OpenAI / GPT-powered chatbots and voice-to-text (Whisper API) → Image recognition with Azure Vision & TensorFlow Lite → Smart search and recommendation engines 🛒 Complex App Features → Stripe & in-app purchase subscriptions (App Store / Play Store billing) → Real-time booking systems with calendar sync and push reminders → Google Maps / Mapbox with geofencing and live location tracking → Multi-role user systems with granular permissions and admin panels APPS I'VE SHIPPED TrinDocs · Crushfit · Slice & Spin · CV Wallet · HBoxTV — and 45+ more TECH STACK AT A GLANCE Mobile → .NET MAUI · Flutter · Xamarin Backend → ASP.NET Core · Node.js · GraphQL · SignalR Cloud → Azure · Firebase · AWS Database → SQL Server · PostgreSQL · SQLite · Firestore DevOps → GitHub Actions · Azure DevOps · App Center · Fastlane HOW WE'LL WORK TOGETHER You send a message describing your project We jump on a free 15-minute discovery call I send a clear proposal with architecture plan, timeline & milestones We build — with weekly demos, clean git history, and zero surprises Ready to build something great?
