[daaimah123]

Problem:
We need to implement a comprehensive user management system that supports different roles (Admin, Applicant, Volunteer) with appropriate access levels and integrates with GitHub for authentication.

Implementation Details:

1. Design and implement a user authentication system
2. Create a role-based access control (RBAC) system for Admin, Applicant, and Volunteer roles
3. Develop login/logout functionality
4. Implement secure password hashing and storage
5. Create user registration and account management features
6. Develop an interface for admins to manage user roles
7. Implement OAuth integration for GitHub authentication
8. Design and implement a database schema for role-based user profiles
9. Create profile extension features to accommodate role-specific information
10. Implement GitHub integration for applicant profiles

Technical Concepts:

• Authentication and authorization systems
• Role-based access control (RBAC)
• Secure password management
• OAuth 2.0 implementation
• Database schema design for user profiles
• GitHub API integration

Dependencies:
Issue 1: Set up project structure and database integration

Acceptance Criteria:

• Users can register, log in, and log out securely
• Different user roles (Admin, Applicant, Volunteer) have appropriate access levels
• Admins can manage user roles through an intuitive interface
• Passwords are securely hashed and stored
• GitHub OAuth integration allows for easy authentication
• System prevents unauthorized access to restricted areas
• User profiles store extended information specific to each role
• Applicant profiles include GitHub integration for assignment submissions
• Volunteer profiles include relevant information for their role in the system
