🚀 Task Management System API

A professional-grade backend built with FastAPI. This project implements a modular architecture, modern Python type hinting, and robust data validation.

---

📌 Project Goals

The Task Management System provides a foundation for team collaboration by managing work items with strict validation rules:

• User Roles: Support for admin, manager, and team_member.
• Task Validation: Custom logic ensuring task titles are always capitalized.
• Data Integrity: Using Literal and Annotated for precise input control.

📸 API Documentation & Testing Screenshots

1️⃣ Interactive API Hub (Swagger UI)

Description: This screenshot captures the FastAPI auto-generated documentation, highlighting the clean, modular organization of User and Task routers implemented using APIRouter. It serves as the central hub for testing all API functionality.

---

2️⃣ Validation Test (Success Case - 200 OK)

Description: This test demonstrates a successful POST request to the /tasks endpoint. The input passes the custom @field_validator logic, which requires task titles to start with a capital letter.

---

---

3️⃣ Error Handling (Validation Error - 422)

Description: Demonstrating the API's robust error handling. A 422 Unprocessable Entity status is returned when validation rules are violated—such as using a lowercase title or an invalid role—ensuring data integrity before processing.
