Service details
I am a Flutter developer with hands-on experience building and maintaining real-world mobile applications.
I have built 3 apps from scratch, contributed to 5 to 6 production apps, and published multiple apps on the Google Play Store both independently and within a company team.
I specialize in short-term, focused tasks that improve your existing app or help you move faster on your project. Whether you need a bug fixed, a new screen built, or a feature integrated, I deliver clean and reliable Flutter code with clear communication at every step.
What I can do for you:
- REST API and Firebase integration
- Bug fixing and issue resolution
- New feature development and code improvements
- Performance optimization and app speed enhancements
- UI fixes and functionality improvements
- Play Store and App Store build preparation
- Real-time features such as chat, notifications, and live updates
- SQLite and local database integration for offline-first apps
How I work:
You share your task, I review it and give you a clear timeline and price. I focus on well-defined, short-term tasks so you get fast delivery without the overhead of a long-term contract. I write clean, maintainable Dart code and keep you updated throughout the process.
The order is not closed until everything works as expected and you are satisfied with the result.
- Message me before placing an order so I can review your task and give you an accurate estimate.
