+- PostgreSQL database + Alembic migrations configured for updating the database when the SQLAlchemy database models are updated
+- Thorough formatting & linting tools
+- Logging, with formatting in both human-readable and JSON formats
+- Backend script that generates a CSV locally or on S3 with proper credentials
+- Ability to run the various utility scripts inside or outside of Docker
+- Restructured and improved API request and response error handling which gives more details than the out-of-the-box approach for both Connexion and Pydantic
+- Easy environment variable configuration for local development using a `local.env` file
