Are you building a mobile app from scratch and need it done right the first time? Or is your existing app built on React Native, Cordova, Ionic, or a legacy native stack and it's costing you time, money, and users? Either way, you're in the right place. I'm Vishal, a Senior Flutter Developer with 9+ years of professional experience, where I've delivered 50+ production-grade mobile apps across industries. Whether you're a founder validating your first MVP, an SME scaling your product, or an enterprise modernizing a legacy system - I build Flutter solutions that are clean, scalable, and built to last. 𝐖𝐡𝐚𝐭 𝐈 𝐒𝐩𝐞𝐜𝐢𝐚𝐥𝐢𝐳𝐞 𝐈𝐧: - App Migration (My Strongest Differentiator) Migrating from an old or unstable stack is one of the most high-risk, high-reward moves a product team can make. I've done it multiple times — successfully: ✔ Cordova → Flutter: Women's Club (business networking app) — crash rate dropped from 8% to under 1%, full feature parity preserved ✔ Flutter GetX → Flutter Bloc: Z Ride (ride-hailing platform, Nigeria) — 45% crash reduction, improved booking reliability, full backend and payment overhaul ✔ Legacy Android (Kotlin/Java) → Flutter: complete cross-platform rewrites with zero data loss I understand the complexity of migrations - legacy code, undocumented APIs, fragile state management, and client anxieties. I de-risk every migration with a structured audit, phased plan, and parallel testing before any cutover. 🚀 Building From Scratch → Startups to Enterprises From idea to App Store / Play Store, I've built complete products end-to-end: ✔ Startups & MVPs: Fast, lean, production-ready. I help founders move from wireframe to live app in weeks, not months. ✔ SMEs: Feature-rich, backend-integrated apps with CMS panels, admin dashboards, role-based access, analytics, and payment systems. ✔ Enterprises: Scalable Flutter apps with complex state management (BLoC, Riverpod), CI/CD pipelines, multi-environment builds, Firebase/Supabase backends, and team collaboration support. Real examples: ✔ Flowkar — Social commerce and creator rewards platform. Built from scratch. Scaled to 100,000+ downloads and 32,000 daily active users across 3 countries. ✔ Evbooth — EV charging platform with real-time charging control, Google Maps, and UPI payment integration. ✔ IPBEE — Healthcare mobile app (rated 5.0 ⭐ by client). 🤖 AI Integration into Flutter Apps AI is no longer a nice-to-have → clients expect it. I integrate AI features directly into Flutter apps cleanly and practically: ✔ OpenAI / GPT-4 chat and assistant features ✔ AI-powered recommendations, smart search, and personalization ✔ On-device ML and computer vision integrations ✔ AI chatbot flows with context-aware conversation management I don't just "add an API call" - I architect the AI layer properly so it's maintainable, cost-efficient, and scalable as your user base grows. 📦 Open Source Contributions on pub.dev I don't just build apps, I contribute back to the Flutter community. I've published production-grade packages on pub.dev under Flexion Infotech. 🌐 Flutter Web & Desktop Flutter isn't just mobile anymore. I build full Flutter Web and Flutter Desktop applications for dashboards, internal tools, admin panels, SaaS interfaces with the same codebase as your mobile app where applicable. This reduces development cost significantly for multi-platform products. 💼 Full-Stack Capability I don't just build the app, I handle the entire product delivery: ✔ UI/UX implementation from Figma, Adobe XD, or Zeplin designs ✔ Firebase (Auth, Firestore, Storage, Cloud Messaging, Crashlytics, Remote Config) ✔ Supabase backend integration ✔ REST API and GraphQL integration ✔ Custom backend development (Node.js, Django, when required) ✔ Payment gateways: Stripe, Razorpay, PayPal, UPI, in-app purchases ✔ Push notifications: FCM, OneSignal ✔ Maps & geolocation: Google Maps, MapKit, real-time tracking ✔ Social login: Google, Apple, Facebook, Instagram ✔ Play Store & App Store publishing, ASO, and update management ✔ CI/CD: GitHub Actions, Bitrise, Fastlane 🛠 Technical Stack State Management: BLoC, Riverpod, Provider, GetX, MobX Architecture: MVVM, MVC, MVP, Clean Architecture, SOLID principles Databases: Firestore, Supabase, SQLite (Sqflite), Isar, SharedPreferences Languages: Dart, Kotlin, Java, Swift (for native integrations) DevOps: Git, GitHub, GitLab, Bitbucket, CI/CD Tools: FlutterFlow, VS Code, Android Studio, Xcode 🏆 Why Clients Choose Me ✔ 100% Job Success Score on Upwork ✔ Top Rated badge & consistent 5-star delivery ✔ Published open-source Flutter packages on pub.dev ✔ 50+ apps delivered across healthcare, fintech, logistics, e-commerce, social platforms, etc. 💬 Let's Talk If you're building something new or rescuing something broken, let's have a quick 30-minute call.

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.
