The Challenge
University learning discussions are often scattered across chat groups and unstructured threads, making it difficult to search past answers or reuse high-quality solutions. CPExchange needed to support technical content (LaTeX, code blocks, file attachments) while keeping discussions organized through Tag/Subtag taxonomy. In addition, educators required strong moderation capabilities—such as verifying answers, removing inappropriate content, and banning users—to maintain trust and content quality as the platform scales.
The Solution
Built a full-stack Q&A platform with a clean, mobile-first interface and a scalable data model for long-term content growth. Implemented rich content support (LaTeX rendering, code blocks, file uploads), structured discussions (posts, comments, replies), and engagement signals (likes, votes, bookmarks). Added role-based moderation for educators/admins to verify answers, remove content, and manage user bans. Integrated real-time notifications via WebSocket to keep users engaged and aware of replies, verifications, and updates.
Key Results
Rich Technical Content Support (LaTeX, code blocks, attachments)
End-to-end Moderation Tools (verify, remove, ban)
Structured Tag/Subtag Taxonomy for discoverability
