Spring Boot Role-Based Security Implementation

I'm looking for a skilled Spring Boot developer to help me set up role-based security for my application. The main goal of this is to ensure proper authorization across different user types.

Here's what I have in mind for this project:

- I need the system to restrict access to various functionalities based on the user's role.
- The application will have three types of users: Administrators, Regular Users, and Guests.
- Among administrators, I need a specific functionality for them to set up role permissions.

Technical Requirements:
- Proven experience with Spring Boot and security implementations.
- Excellent understanding of role-based access control.
- Strong knowledge of setting up and managing user roles.

I'm looking forward to collaborating with a professional who can ensure the security and authorization aspects of my application are well taken care of. Thank you.
