I'm working on a new project called CS Revise, a full-stack web application designed to help IB Computer Science students prepare for their exams. The app will include features such as user authentication, a user dashboard with statistics, practice pseudo code and Java exercises, topic-specific tests, mock exams, term revision with live marking, an AI chat for learning and clarifying doubts, and user progress tracking. I haven't finalized the tech stack yet, so I'm looking for your recommendations on what technologies and tools would be best to use for the frontend, backend, database, authentication, AI integration, and overall development. Any suggestions or feedback would be greatly appreciated!
