Fultter app developer

I am looking for a skilled Flutter app developer who can create a complex app with advanced features. The app needs to be developed for both iOS and Android platforms. I already have existing designs for the app, so design assistance is not necessary.

Ideal Skills and Experience:

- Experience in developing complex apps with advanced features
- Knowledge of both iOS and Android platforms
- Ability to work with existing designs and implement them effectively
