This is a TypeScript implementation of a multi-user chat system, built to practice and demonstrate low level design (LLD) skills. It is not a fully functional server — there is no real HTTP server, no database, and no WebSocket layer. The goal here is clean architecture, proper OOP, and well-thought-out authorization logic.

Low level design of chat application

Several network systems are built to communicate with one another as well as made available through service-oriented architectures. In this project, the client server architecture is used to develop a chat application. Firstly a chat application is created for both Client and Server which is based on Transmission Control Protocol (TCP) where TCP is connection oriented protocol and is a reliable connection protocol​ . ​ The design is very simple. It is implemented in java, since is easy to program in,it precludes the need to deal with low-level memory management and includes powerful libraries for sockets and threads.

A real-time WebAssembly-powered chat application using C, WebSockets, and WASM. Designed for fast and efficient messaging with minimal latency, leveraging low-level performance optimizations.

A private lab for experimenting with application-layer protocol design and low-level network programming. This repository incrementally builds reusable socket abstractions and multiple networked systems (chat, Http)

VoxLink is a real-time chat application designed to improve accessibility and communication by integrating a Text-to-Speech (TTS) system. It is especially helpful for people with low literacy levels or visual impairments by allowing them to hear messages instead of reading them
