Design Rationale

The chosen tech stack (React, Node.js, PostgreSQL) offers a balance of performance, scalability, and developer productivity. React's component-based architecture allows for reusable UI elements, while Node.js provides a fast and efficient backend. PostgreSQL was selected for its robustness in handling complex data relationships.

The Automated Blog Post Featured Image Generator is integrated as a core feature to differentiate this social platform and provide unique value to content creators. This feature aims to streamline the content creation process and enhance the visual appeal of posts.

Real-time features like messaging and notifications are implemented using WebSockets to create a dynamic and engaging user experience. The modular file structure and use of modern development practices (e.g., containerization, CI/CD) ensure maintainability and ease of future enhancements.
