Freelancer to merge driver and customer apps into a single application

Hello, how are you?

I am looking for an experienced freelancer for a specific and straightforward task.

I already have the complete source code of a ride-hailing application (Uber/InDriver style), currently separated into two apps:

Customer App

Driver App

Project goal

Merge the two applications into a single app, where:

The user can choose to log in as Customer or Driver

All existing functionalities are preserved

No core logic is broken

Important:
This is not a new app from scratch.
The system is already complete and working.
The task is only to organize, integrate, and unify both apps into one.

Scope of work

Merge both projects into a single application

Create a profile selection (Customer / Driver) at login or initial menu

Ensure all current features continue to work properly

Clean, organized, and stable code

Do not change existing business rules

Language and location

Application in Portuguese (Brazil – pt-BR)

Map configured and centered on Brazil by default

Technologies

Project already developed (Flutter / mobile)

Backend and admin panel already exist

Information required in your proposal

Experience with Flutter and ride-hailing apps

Estimated delivery time

Service cost

Post-delivery support availability (even basic)

If the work is well executed, there is potential for future projects and a long-term partnership.

I look forward to your reply.
Thank you!
