Design Rationale

The project combines social networking with posture monitoring to create a unique, health-focused platform. React was chosen for its component-based architecture and large ecosystem, while Node.js provides a JavaScript-based backend for consistency. PostgreSQL offers robust relational data storage for complex social relationships. The Smart Chair integration uses WebSockets for real-time communication, ensuring immediate posture feedback. The gamification elements aim to increase user engagement and motivation for maintaining good posture. The deployment strategy prioritizes scalability and reliability to support potential rapid growth of the user base.
