CodeDuel: A Real-Time Competitive Coding Platform

CodeDuel, a real-time competitive coding platform.

CodeDuel, a real-time competitive coding platform. It is offered as a reference project: a complete, worked example of how a system like this is designed, built and evaluated, so that a developer can study it, run it and learn from it.

It suits learners building full-stack skills: user accounts and roles, a database-backed back end, a responsive front end and deployment.

The main parts are real-time processing of incoming data, secure sign-up with role-based access, a database-backed back end with a clear API, a responsive interface for each type of user, and an admin view to manage records. The reference build uses Apache Kafka, React, Node.js, Express, and PostgreSQL, with a clear project structure, setup instructions and sample data so that it can be run and extended.
