# Tech Stack
- Prefer Postgres database, but ask user
- For new backend projects: use .NET for structured enterprise/API services, Python for data/ML/scripting tasks, Rust for performance-critical components. For existing projects, use the language already established in that project.
- For the frontend, use React with Tailwind css (or even plain css, if it is a simple project)
- document api with OpenAPI
