🧠 ITAG Backend API

A robust and scalable backend API built with Node.js and Express, designed to manage authentication, users, jobs, reports, and media services.
This project provides a well-structured MVC architecture with secure middleware, efficient database integration, and reusable service modules.

---

🚀 Overview

ITAG Backend serves as the core API for the ITAG ecosystem — handling all server-side logic, authentication, admin management, and CRUD operations for users, jobs, and multimedia content.

It follows clean architecture principles and is production-ready for deployment with Docker, PM2, or cloud environments like AWS, Vercel, or Render.
