About this gig
Built an app with AI, FlutterFlow, Lovable, Bolt, Cursor or ChatGPT, but its not ready for real users?
I help founders turn AI-generated MVPs into production-ready mobile apps for iOS and Android.
Many AI-built apps work as demos but struggle with scalability, performance, architecture, backend integration, authentication, data management, and app store deployment.
Services:
- Flutter mobile app development
- Bug fixing & app rescue
- MVP rebuilds & architecture improvements
- Backend & API integration
- Firebase, Supabase & custom backends
- Authentication & user accounts
- Media uploads & cloud storage
- Performance optimization
- App Store & Google Play deployment
Perfect for:
- AI-generated apps that need professional development
- FlutterFlow projects requiring custom code
- Startup MVPs preparing for launch
- Existing apps needing maintenance or rebuilding
- I build mobile apps with scalable architecture, production backends, authentication, media uploads, analytics, notifications, and real-world reliability.
Technologies: Flutter, Kotlin, Firebase, Supabase, PostgreSQL, REST APIs, AWS, Android, iOS.
Send me a message and I'll review your project before we start.

FAQ
What do you need from me to start the project?
Please provide a clear app idea or concept, any design files (Figma, sketches), and details about features or backend requirements. The more detailed you are, the faster I can deliver.
Will I get the full source code?
Yes! I provide clean, well-structured source code with every package so you have full ownership of your app.
How long will it take to build my app?
Delivery times vary by package: Basic apps take about 4 days, Standard apps around 6 days, and Premium apps 8–10 days. While I always strive to deliver on or before the deadline, the most important thing for me is your full satisfaction and a well-functioning, polished app that meets your needs.
Can you add new features after delivery?
Yes! I offer ongoing support and updates as separate custom orders or maintenance gigs. Revisions during the project cover minor changes only.
What if I need help with backend or API development?
I can develop RESTful APIs using Ktor and PostgreSQL, and integrate them seamlessly with your Android app. This is included in my Standard and Premium packages or available as a custom offer.
Do you provide app design or just development?
I can implement UI/UX designs from your provided mockups or Figma files. If you need full design services, I can recommend trusted designers or collaborate with your team.
What platforms do you develop for?
I develop cross-platform mobile applications for both Android and iOS using Flutter. I also have experience with native Android development using Kotlin and Jetpack Compose, allowing me to build scalable, high-performance mobile solutions tailored to your needs.
