@04shubham7 assign this issue to me I want to implement RBAC to your project
For doing this I will
Add a role field to your user model (e.g., Senior, Junior).
Create a middleware that checks user’s role before allowing access.
Apply that middleware to selected routes.

@04shubham7 Assign it to me below is the strategy
Add an Authentication Controller to manage user signup, login, token refresh, and logout using JWT.
It should integrate with the existing JWT middleware for role-based access.
Include secure password hashing, role assignment, and routes for fetching the current authenticated user.
This will centralize and simplify authentication logic across the app.
Use an role based-model for different types of users
I have created the middleware so I can update the routes as well and add controllers to it.
Use an role based-model for different types of users
