Sustania was developed as a prototype for an augmented reality game focused on sustainability and urban environmental awareness. The project aimed to connect real-world environments with interactive gameplay driven by live environmental and geospatial data.

The concept combines AR gameplay with real-world data sources, such as satellite imagery and weather data, allowing players to explore their surroundings, complete location-based objectives, and make decisions related to urban sustainability.

The primary focus of the project was backend architecture and system design. A scalable API was developed using FastAPI, supported by a PostgreSQL database hosted on Neon. The system was designed to handle persistent data, user interaction, and real-time game state, following principles similar to MMO-style backend services.

Deployment and infrastructure were an important part of the implementation. The backend was containerized using Docker and deployed to a cloud environment, with attention given to configuration, reliability, and ease of iteration during development.

Although the project remained at a prototype stage, it demonstrates experience in designing and implementing backend systems, deploying real-world services, and working with data-driven applications under time constraints.

Contribution

Designed the system architecture, database schema, and API structure; implemented core backend services using FastAPI; handled authentication and security design; containerized the backend using Docker and deployed it; contributed to early Godot-based prototype development and environment effects.
