Yapp
A real-time, full-stack chat application built for instant messaging and seamless communication
What is it?
Yapp is a modern real-time chat application designed for simple, fast, and seamless communication. It allows users to create accounts, search for other users, and engage in one-on-one or group text conversations in real-time, supported by an intuitive and responsive UI.
What I Did
I engineered both the client and server applications from scratch. I implemented real-time bidirectional communication, designed the database schema for messages and users, handled state management on the frontend, and built secure authentication to protect user conversations.
