🚀 SENIOR FLUTTER DEVELOPER | EXPERT FLUTTERFLOW & BUBBLE DEVELOPER | 7+ Years | 40+ Apps Shipped | $100K+ Earned | 100% Job Success
Looking for a Flutter, FlutterFlow, or Bubble developer who can take your idea from MVP to a production-ready product? I help startups and businesses build scalable mobile apps, SaaS platforms, and marketplaces using the right technology for the job. Whether it's Flutter for high-performance mobile apps, FlutterFlow for rapid development, or Bubble for web-based SaaS products, I focus on building solutions that are reliable, maintainable, and ready to grow with your business.
Over the past 7+ years, I have helped startups and businesses build 50+ mobile applications used by thousands of users across healthcare, fintech, SaaS, e-commerce, logistics, education, marketplaces, and consumer products. Whether you need a brand-new MVP, new features for an existing application, or someone to rescue and scale a growing codebase, I can help.
I focus on building production-ready Flutter applications that are clean, maintainable, scalable, and easy for future developers to work with.
My experience includes:
FLUTTER DEVELOPMENT
• Flutter App Development for iOS, Android, and Web
• Cross-Platform Mobile App Development
• Pixel-perfect Flutter UI from Figma
• Firebase Authentication, Firestore, Cloud Functions, Cloud Messaging (FCM), Hosting, Crashlytics and Analytics
• REST API Integration and third-party SDK integration
• RevenueCat subscriptions
• Stripe, PayPal, and In-App Purchases
• GetX, Riverpod, Provider and Bloc
• MVVM, MVC and Clean Architecture
• Offline-first applications
• Push Notifications
• Google Maps and Location Services
• AI-powered applications using OpenAI and modern LLMs
• App Store and Google Play deployment
• Performance optimization and bug fixing
• Flutter app modernization and long-term maintenance
I also specialize in taking over existing Flutter projects. Many of my clients come to me when their previous developer has left, the codebase has become difficult to maintain, or new features need to be added without introducing technical debt. I quickly understand existing architectures, improve code quality, and continue development with minimal disruption.
Beyond Flutter, I help founders choose the right technology for their business.
FLUTTERFLOW
When speed is the priority, I build MVPs in FlutterFlow while extending them with custom Flutter code whenever the visual builder reaches its limits.
BUBBLE
For web-first SaaS products and marketplaces, I build scalable Bubble applications with complex workflows, API integrations, Stripe payments, Xano backends, Airtable, automation, and third-party services. I have 4 years of BUBBLE DEVELOPMENT experience.
I believe technology should fit the business, not the other way around. If Flutter is the best solution, I will recommend Flutter. If Bubble or FlutterFlow gets you to market faster and saves you money, I will tell you that instead.
Why clients enjoy working with me:
✓ 7+ years of professional mobile app development experience
✓ Strong communication and fluent English
✓ Comfortable on Slack, Jira, or wherever your team already works
✓ Clean, scalable, well-documented code
✓ GitHub/GitLab pushes from day one so you own the IP
✓ Regular progress updates throughout development
✓ Long-term support after launch
I use modern AI-assisted development tools, including Cursor, Claude, and ChatGPT, to automate repetitive tasks, improve code quality, and deliver features more efficiently. That means more time is spent solving your business problems rather than writing boilerplate code.
Whether you are:
• Building your first MVP
• Launching a startup
• Scaling an existing Flutter application
• Migrating from another technology
• Looking for a long-term Flutter developer
• Building a web based platform using Bubble
• Creating an AI-powered mobile app
I would be happy to discuss your project and recommend the best technical approach before development begins.
Send me a message, and let's build something your users will love.

Flutter apps usually break in the boring places: Firebase rules, API responses, payment states, push notifications, app-store builds, and the logic between screens.
I work as a Flutter Developer for Android/iOS apps where the goal is not just a working preview, but a clean, testable app clients can launch.
I build and improve mobile apps using Flutter, Dart, FlutterFlow, React Native, BLOC/Riverpod state management, Firebase, Supabase, REST APIs, payments, real-time chat, push notifications, and App Store / Play Store deployment workflows.
My best fit is usually one of these situations:
• You have a Figma design and need it converted into a real Flutter or FlutterFlow app.
• Your FlutterFlow app is partially built, but the Firebase, API, payment, or app logic is stuck.
• Your Flutter app needs bug fixing, performance cleanup, UI polish, or redeployment.
• You need an MVP for Android/iOS, but you want the structure clean enough to grow after launch.
• You want AI features such as ChatGPT/OpenAI API, AI chat, AI assistants, or automation inside a mobile app.
What I can handle:
• Flutter mobile app development for Android and iOS
• FlutterFlow app development for MVPs, SaaS apps, marketplaces, booking apps, and dashboards
• Firebase setup: Authentication, Firestore, Storage, Cloud Functions, security rules, and push notifications
• Supabase setup: auth, database, APIs, and app integration
• REST API and third-party integrations
• Stripe, Razorpay, PayPal, in-app purchases, and subscription flows
• Real-time chat, booking flows, order tracking, maps, user profiles, admin panels, and notification systems
• App Store and Google Play release support
Common app types I work on: eCommerce and marketplace apps, restaurant and food delivery apps, booking and service apps, dating and social apps, education apps, health and fitness apps, SaaS MVPs, and AI-powered mobile apps.
Clients usually hire me when they need someone who can look beyond the screen design and make sure the app logic, backend, integrations, and launch steps are actually connected properly.
If you need a Flutter Developer who can build, fix, or launch your Android/iOS app with Flutter, FlutterFlow, Firebase, APIs, and payments handled cleanly, send me the app details, and I will suggest the best next step

If you're building a mobile product that needs to ship fast, scale reliably, and actually get used, I build it.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Most mobile developers hand you a codebase. I hand you a product, architected to grow, tested to perform, and built so your next developer won't rewrite everything from scratch.
I work primarily in Flutter with Clean Architecture and BLoC as my default. Every app I ship is maintainable from day one.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AI INTEGRATION
☉ OpenAI / Gemini / Claude API (chat assistants, smart recommendations)
☉ On-device ML with TensorFlow Lite and ML Kit
☉ OCR and AI-powered document scanning
☉ Voice recognition and image analysis
☉ Predictive features and personalization layers
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I BUILD
✅ Cross-platform Flutter apps (iOS, Android, Web), MVP to production
✅ FlutterFlow development and FlutterFlow-to-Flutter migration
✅ Architecture setup: Clean Architecture, BLoC, Riverpod, MVVM
✅ Firebase integration (Auth, Firestore, Functions, Analytics, FCM)
✅ Payment integration: Stripe, RevenueCat, Apple Pay
✅ AI feature integration: chatbots, voice assistants, on-device ML
✅ Maps and location: Google Maps, geofencing, live tracking
✅ CI/CD setup: GitHub Actions, Codemagic, App Store + Play Store
✅ App performance audits, rewrites, and architecture migrations
✅ Post-launch support and long-term maintenance
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHO THIS WORKS BEST FOR

· You have a Flutter app that's grown messy and needs a proper architecture rewrite
· You want AI features (chatbot, voice, recommendations) integrated into your existing app
· You built in FlutterFlow, hit its limits, and need someone to migrate to production Flutter
· You need full ownership, not just a developer waiting for tickets
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHY CLIENTS CHOOSE ME
✔ Clean Architecture + BLoC by default, no messy code to inherit
✔ AI-ready, I build smart features not just screens
✔ FlutterFlow to Flutter migration when you've outgrown no-code
✔ Long-term reliability, most clients return for multiple projects
✔ Clear communication, fast responses, zero surprises
