QueeTalk is a full-featured real-time chat application supporting both personal and group conversations. It was developed with a focus on speed, security, and seamless user experience, catering to over 200 users. The platform features two-factor authentication (TOTP), secure JWT-based sessions, and efficient Redis caching for socket connections. The user experience was enhanced by adding typing indicators, file sharing, emoji picker, and emoji reactions, improving engagement by 35%. Chatty achieved a message latency of under 200ms through Redis caching and file upload rate-limiting. It follows a clean Model-View architecture using Node.js and Socket.IO for real-time communication, with MongoDB as the primary data store. All media attachments are uploaded to and served from a Cloudflare R2 Bucket, ensuring fast and secure access.
