sobhagyaverma/codeit ? reverse-engineered prompt

Build me a full stack coding practice platform like CodeT, where users can sign up, log in, browse problems, write code in a nice editor, run sample tests, and submit for hidden test judging. I want timed contests with live leaderboards, plus shared coding rooms where two or more people can chat, see each other online, and work together in the same editor and whiteboard.

Please also include an admin area where I can create and manage problems and competitions, and a simple AI coach that can explain solutions, give hints, and review mistakes. Make the app feel polished and modern, with a clean dashboard, profile settings, and support for multiple programming languages.

Use the stack that fits this project, with a React and TypeScript frontend, a Spring Boot backend, PostgreSQL, Redis, JWT login, WebSockets for live updates, and a real time sync service for collaborative editing. If you need to look up current docs online, go ahead.
