Backend API for user authentication, access control, account management, and protected application resources.
Description
AuthCore API is a backend service designed to centralize user authentication and access control for web applications. The project manages user accounts, credentials, protected routes, roles, and permissions through a structured REST API.
The main objective was to create a reusable authentication backend that could serve as the security layer for different applications without coupling authentication logic directly to the frontend.
My Role
As the Backend Developer, I designed and implemented the authentication flow, database structure, access control, request validation, and API endpoints responsible for managing users and protected resources.
- Developed endpoints for user registration, authentication, and logout.
- Implemented secure password storage and credential validation.
- Created protected routes accessible only to authenticated users.
- Implemented role-based access control for different types of users.
- Developed user account management operations.
- Added request validation and structured error responses.
- Integrated PostgreSQL for persistent user and authentication data.
- Organized the backend following a modular API structure.
Key Features
- User registration and authentication.
- Secure password management.
- Protected API routes.
- Role-based authorization.
- User profile management.
- Input validation.
- Structured API responses.
- Error handling.
- PostgreSQL data persistence.
- RESTful endpoint architecture.
Example Endpoints
| Method | Endpoint | Description |
|---|---|---|
| POST | /api/register | Create a new user account |
| POST | /api/login | Authenticate a user |
| POST | /api/logout | End the authenticated session |
| GET | /api/user | Retrieve authenticated user information |
| PUT | /api/user | Update user information |
| GET | /api/users | Retrieve users with authorized access |
| GET | /api/roles | Retrieve available user roles |
Security
The API was designed with authentication and authorization as its main focus. Passwords are securely hashed before being stored, incoming data is validated before processing, and protected endpoints verify user permissions before allowing access to application resources.
Impact
AuthCore API provides a reusable authentication foundation for web applications, separating security and user-management responsibilities from the frontend. This architecture simplifies the development of applications that require authentication, protected resources, and different levels of user access.
