Design Rationale

The design decisions for this project prioritize user engagement, data accuracy, and scalability. React was chosen for its component-based architecture, allowing for a modular and maintainable frontend. D3.js provides powerful data visualization capabilities, essential for making complex carbon footprint data accessible and meaningful to users.

The Node.js backend with Express offers a lightweight and efficient server solution, while PostgreSQL provides a robust, relational database system capable of handling complex queries and relationships necessary for user data and carbon logs.

Docker containerization ensures consistency across development and production environments, simplifying deployment and scaling. The use of AWS services provides a reliable, scalable infrastructure that can grow with the application's user base.

The focus on real-time updates and interactive visualizations aims to keep users engaged and motivated in their carbon reduction journey. By combining personal tracking with community features, the application encourages sustained use and promotes a collective effort towards environmental sustainability.
