I specialize in building scalable, production-ready mobile applications using Flutter and Dart. With 8+ years of full-cycle mobile development experience, I help businesses build new mobile products, improve existing Flutter applications, and solve complex platform-specific challenges across iOS and Android. I do more than implement UI screens. I design maintainable application architecture, optimize performance, integrate native platform functionality, and support applications through App Store and Google Play release. CORE FLUTTER AND DART ENGINEERING Scalable Architecture: I use Clean Architecture and predictable state-management patterns, primarily Riverpod and BLoC, to keep UI, business logic, and data layers clearly separated. Native and Platform Integrations: I build custom platform-channel integrations when standard Flutter packages do not meet the project requirements. My experience includes background geolocation, native device APIs, platform-specific SDKs, and custom Mapbox mapping workflows across iOS and Android. Performance Optimization: I profile widget rebuilds, investigate rendering bottlenecks, identify memory issues, and improve performance in data-heavy and interaction-heavy Flutter applications. MOBILE ECOSYSTEM INTEGRATIONS Authentication and Real-Time Data: I implement authentication, role-based access control, secure token handling, real-time data updates, and cloud synchronization using Firebase and Supabase. Subscriptions and Payments: I integrate RevenueCat, Apple StoreKit, Google Play Billing, and Stripe for subscriptions, in-app purchases, purchase restoration, payment flows, and subscription lifecycle management. Offline Data: I build offline-first data flows using SQLite and Hive, including local caching, secure storage, background synchronization, and conflict-handling strategies. Notifications and Deep Linking: I implement Firebase Cloud Messaging, local notifications, deep links, universal links, notification routing, and background notification handling. APPLIED AI IN FLUTTER APPLICATIONS AI API Integration: I integrate AI capabilities into Flutter applications using OpenAI and Claude APIs. This includes conversation-history management, prompt-context handling, token-usage monitoring, structured responses, and secure communication with the application’s AI services. On-Device Models: When privacy, latency, or offline availability matters, I can integrate supported on-device machine-learning models into Flutter applications for tasks such as classification, image analysis, document processing, and structured data extraction. WHY CLIENTS WORK WITH ME • 8+ years of mobile development experience with strong Flutter and Dart specialization • Direct communication with the developer responsible for your implementation • Practical technical recommendations based on real business requirements • Clean, maintainable, and well-structured Flutter code • Clear documentation and regular progress updates • Support from planning through deployment and post-launch maintenance • CI/CD setup, App Store publishing, and Google Play release support I can help you build a new Flutter application, improve an existing codebase, integrate complex mobile features, resolve performance issues, or prepare your application for App Store and Google Play release. Send me a brief overview of your application, its current stage, and its main technical challenges. I will help you evaluate the requirements and identify the most practical path forward.
