ChatWave
Full-Stack Real-Time Chat Application
Production-ready real-time chat platform built with React.js and Node.js, demonstrating expertise in event-driven architecture, WebSocket communication, and scalable backend design. The application handles high concurrent user loads with optimized performance and enterprise-grade security.
Key Features & Technical Implementation
- •High-Performance Real-Time Communication: Built a React.js + Node.js chat platform handling 500+ concurrent users with sub-200ms latency using Socket.io
- •Event-Driven Architecture: Designed event-driven architecture with message compression and 40% bandwidth reduction via binary protocol optimization
- •Enterprise-Grade Security: Secured sessions using JWT authentication, token rotation, and AES-256 encryption for MongoDB Atlas storage
- •Modern UI/UX: Created responsive Chakra UI interface with theme switching and accessibility compliance
- •Advanced Features: Implemented group chat CRUD operations, role-based access control, and Redis caching for participant lists
