Driver Trip Cancellation Fee Development

I need a seasoned backend Java and Spring Boot developer to implement a key feature in my project before Monday. This feature deals with the Driver trip cancellation fee.

The specific task involves:
- Creating a system for manual fee adjustment
- Updating driver ledger in current project.
- Integrating with Razorpay to facilitate payment
- accept and reject flow.

The ideal candidate should be experienced with:
- Backend development in Java
- Using Spring Boot
- Building payment systems with Razorpay, particularly online payment and if its offline then sending a link for payment.

This project is a precursor to a long-term collaboration.
