ProNet is a minimal yet professional client-server application built in modern C++ using Winsock and CMake. It enables structured peer-to-peer message exchange using JSON (via json.hpp) without relying on third-party libraries like Boost. It's designed to showcase clean architecture, real-time communication, and professional code organization in a native Windows environment.

A lightweight C++ client-server networking application built using the Winsock API on Windows. This project demonstrates the networking fundamentals, socket programming, and clean software design principles. The app simulates a basic professional networking platform where users can connect and exchange messages.

This project is designed to showcase:

• Understanding of TCP socket communication using Winsock.
• Clean separation of concerns between client and server logic.
• Well-structured code with modern C++ practices.
• Readable, documented code with proper error handling.

It can be extended to support multiple clients, user registration, or even integrate a database in the future.
