CodeQuery is a full-stack MERN Developer Q&A platform inspired by community-driven knowledge-sharing websites like Stack Overflow. The platform enables developers to ask questions, share solutions, engage in discussions, and collaborate within a structured technical community.
\nBuilt with React, Node.js, Express.js, and MongoDB Atlas, CodeQuery incorporates an AI-powered moderation system using Groq LLM to automatically detect abusive, toxic, and spam content. To maintain a healthy community environment, the platform includes an automated strike-based enforcement system that permanently blocks users after repeated violations.
\nThe application features secure JWT authentication, bcrypt password hashing, custom rate limiting for abuse prevention, full-text search, real-time notifications, and a comprehensive admin dashboard for content moderation and user management. Designed with scalability, security, and real-world community management principles in mind, CodeQuery demonstrates the implementation of modern full-stack development practices, AI integration, and platform moderation systems.
