Android Taxi App with Dynamic Fare System

I'm looking for a skilled mobile app developer to create an Android-based taxi application. This application should include a complex fare calculation system designed to be fair and profitable for both drivers and passengers.

Key Features:
- The app should support three user roles: Driver, Passenger, and Admin.
- A complicated fare calculation: The base fare starts at ₹100, every 6 minutes adds ₹10, and each km driven costs ₹6.
- The base fare should reset to zero if the car is driven for 1 hour.
- The fare displayed should be consistent across both the user and driver interface.

Essential Integrations:
- Payment gateway for seamless transactions.
- Map services for navigation and location tracking.
- A messaging system for communication between users.

Ideal skills for this project would be:
- Proficiency in Android app development.
- Experience in creating multi-user role applications.
- Knowledge of integrating third-party services.
- Understanding of fare calculation systems in transport apps.

The app should have a user-friendly interface with easy navigation and clear icons. The user interface should have a modern and sleek design. "Based on your preference for a simple and clean UI, please consider incorporating this into the fare system."
