I will develop a cross platform mobile app using flutter


Level 1
About this gig
I'm a Flutter developer with 5+ years of experience building and shipping cross-platform mobile apps including apps live on both the Google Play Store and Apple App Store.
I don't just build the UI. I can develop your entire app end-to-end, including:
- Flutter apps for Android and iOS from a single codebase
- Custom ASP.NET Core backend & REST API integration
- Firebase authentication and real-time database integration
- Stripe payment integration with 3D Secure support
- Real-time features like chat and live notifications (SignalR/Socket/Web-socket/FCM)
- Clean Architecture with Riverpod state management for scalable, maintainable code
- CI/CD pipeline setup (GitHub Actions) for automated builds and store deployment
Bonus: Figma UI/UX design, and seamless Figma-to-Flutter conversion.
I work with startups, small businesses, and enterprise clients who need more than just a pretty interface a fully working product they can actually launch and scale.
Message me with your idea and I'll walk you through the best approach for your app.

FAQ
Do you only build the app's UI, or can you handle the backend too?
I handle both. Alongside Flutter development, I build custom backends using ASP.NET Core, including REST APIs, authentication, and database design — so you get a fully working app, not just a frontend.
Can you integrate payments into my app?
Yes, I integrate Stripe payments including 3D Secure (3DS) support for secure, compliant transactions.
Do you build real-time features like chat or live notifications?
Yes, I use SignalR to add real-time chat, live notifications, and other live-updating features to apps.
Will I get the source code after the project is done?
Yes, full source code is included in every package, along with clean, documented, maintainable code using Clean Architecture principles.
Can you publish my app to the Google Play Store and Apple App Store?
Yes, app store submission is included, and I have experience publishing apps successfully on both platforms.
Do you offer UI/UX design as well, or do I need to provide designs myself?
I can design your app in Figma and convert it directly into Flutter, or work from designs you already have — whichever fits your project.
