Secure Task Management Backend built with ASP.NET Core 8 + PostgreSQL
TaskFlow API is a production-style backend service designed to demonstrate real-world backend development expertise. It implements secure, role-based task management and exposes a clean REST API suitable for integration with frontend applications or other services.
The project showcases enterprise-grade backend architecture including authentication, authorization, structured data handling, and API documentation.
- JWT Authentication: Secure login and token-based authorization for users.
- Role-Based Access Control: Admin, Manager, and User roles with appropriate permissions.
- Task Management: Create, read, update, and delete tasks with support for pagination and filtering.
- PostgreSQL Integration: Persistent relational database using Entity Framework Core.
- Global Error Handling: Centralized exception management for consistent API responses.
- Swagger / OpenAPI Documentation: Interactive API documentation for testing and exploration.
The API provides endpoints to handle:
- User Authentication: Registration and login with JWT token issuance.
- Task Operations: CRUD operations for tasks, with role-based restrictions.
- Secure Access: Endpoints are protected and require proper authorization tokens.

This project wants to demonstrates:
- Professional backend design patterns: Clean architecture, layered services, and dependency injection.
- Security best practices: JWT authentication, hashed passwords, and role-based access control.
- Database expertise: Designing relational data models and working with EF Core.
- API design skills: RESTful endpoints, structured responses, and error handling.
The TaskFlow API is designed to be scalable and extensible. Planned future enhancements include:
- Task Comments & Attachments
Enable users to add notes or files to tasks, improving collaboration and task context. - Task Analytics & Dashboard
Provide endpoints for task statistics, completion rates, and user performance metrics. - Email Notifications
Notify users of task assignments, updates, and upcoming deadlines to improve workflow efficiency.
