Muhammad Z.

Top Rated Flutter Developer with 5+ years of experience building and shipping production mobile apps for iOS and Android. I’ve delivered 20+ production apps with a 100% Job Success Score on Upwork. My primary focus is Flutter and Dart, complemented by hands-on experience with Swift, SwiftUI, and Kotlin for platform-specific features. I build Flutter applications from Figma and product requirements through development, API integration, testing, performance optimization, and App Store and Google Play deployment. I can help with: Flutter app development for iOS and Android Flutter UI development and responsive layouts Figma to Flutter implementation REST API and third-party API integration Firebase and Supabase Authentication and real-time features SQLite, local storage, and offline-first apps Push and local notifications Payments, subscriptions, and in-app purchases Google Maps, GPS, and location services Performance optimization and debugging App Store and Google Play deployment For larger Flutter applications, I use Clean Architecture, MVVM, SOLID principles, and state management solutions such as BLoC, Riverpod, Provider, and GetX to keep the codebase organized and maintainable. When a project requires platform-specific functionality, I can work directly with Swift, SwiftUI, and Kotlin. My experience includes iOS SDK integrations, platform channels, background services, WidgetKit, Apple Watch, CarPlay, and wearable integrations. One of the projects I’ve worked on is a Flutter-based Islamic prayer and lifestyle application with integrations across the Apple ecosystem, including iOS, Apple Watch, Home Screen Widgets, CarPlay, and wearable/smart-ring functionality. I’ve worked on Flutter applications across FinTech, e-commerce, SaaS, marketplaces, healthcare, camera and video, business applications, Islamic/lifestyle products, and IoT. I also have experience integrating AI-powered features into Flutter applications using OpenAI and Gemini APIs. I use modern development tools such as Cursor and Lovable where they help speed up development without compromising the quality of the final codebase. Whether you need a new Flutter application, improvements to an existing app, API or payment integration, difficult Flutter bugs fixed, or platform-specific functionality added, I can help. If you have a Figma design, requirements, or an existing Flutter project, send it over and we can discuss the right approach.
