CodeAscend

CodeAscend is an interactive platform designed for developers to engage in competitive coding challenges, enhance their problem-solving skills, and climb the ranks in real-time coding battles. Whether you're a beginner or an experienced coder, CodeAscend provides a fun and challenging environment to test your abilities in problem solving through head-to-head matches, tournaments, and dynamic coding challenges.

Project Structure

• Frontend: Built using React and TypeScript.
• Backend: Node.js and Express, handling APIs and Socket.IO for real-time matchmaking.
• Database: PostgreSQL for storing user data, problem sets, and match results.
• Monorepo: Organized using apps (for web and server) and packages (for UI, tsconfig).
