🐳 Docker Deployment

The entire stack can be launched with a single command:

docker compose up --build

• Frontend: http://localhost:5173
• Backend: http://localhost:8080
• Postgres: localhost:5432
• Redis: localhost:6379

🧪 CI/CD

Automated builds and tests are handled via GitHub Actions (.github/workflows/ci.yml), ensuring that every push to main is buildable and robust.

A Note on the deployment:

If you're reading this after mid-Apr26, you'll likely hit an error with the URL as my GCP trial would expire by then.
