Backend_Delta

Backend for the Delta project, implemented in C++ using Qt and custom HTTP routing.
This repository provides the server-side logic and endpoints consumed by the frontend.

⚠️ This project is designed to run on port 8080.

---

🚀 Purpose

This backend handles:

• User authentication (registration, login) via JWT
• RESTful API routes for modules like exams, calendar, forum, problems, dashboard, visualizations, rankings, etc.
• SQLite database operations
• Consistent API responses
