Cross-Platform Ride-Hailing App Development

I need a skilled developer (or team) to create a ride-hailing mobile app, akin to Bolt or inDrive, covering both Android and iOS platforms.

The app consists of:
- A passenger app featuring in-app chat
- A driver app including driver ratings
- A web-based admin panel for user management, trip management, and analytics and reporting
- Robust server and database integration
- Basic GPS and map functionalities

Key requirements:
- A simple and clean UI/UX
- Full source code delivery
- Previous experience with ride-hailing or delivery app development will be highly advantageous

Given the constraints of my budget, I am seeking quality work at an affordable rate.

If you're interested in this project, please provide:
- Your portfolio, specifically any similar apps you've developed
- A timeline and cost estimation
- Your preferred technology stack (such as Flutter, React Native, etc.)

I am eager to start this collaboration. Thank you.
