Flutter Taxi App Development

I'm looking for an experienced Flutter developer to create a taxi booking application, similar to Uber, for both iOS and Android platforms.

Essential features include:
- Real-time tracking
- In-app payment
- Driver and passenger profiles

The app requires a custom design, so a strong background in UI/UX design is preferred.

Ideal skills and experience:
- Proficiency in Flutter
- Experience with real-time tracking and payment integration
- Strong UI/UX design skills
- Previous work on similar mobile applications

Please share your portfolio and relevant experience.
