messengerServer

A backend server for a distributed messaging system — the core component handling client requests, managing user sessions, and enforcing business logic for real-time messaging. Demonstrates advanced skills in server-side development, network programming, and scalable backend architecture.

Features Handles real-time messaging logic and client connections Manages user sessions and authentication Organizes routing and business rules for message delivery and persistence Modular project structure for extensibility Tech Stack

This project uses:

Node.js – JavaScript runtime environment

Express (or similar Node.js backend framework) – routing & HTTP handling

Middleware modules – for request validation, auth, etc.

Controllers, DTOs, Models, Services – clean application structure (See project folders for implementation details)
