Built by:

Jens, an intern

Build time:

2 hours 52 minutes

Built with:

a no-code builder on a personal account

Database:

Git commits, technically append-only

Authentication:

production is technically the test environment

Deployment:

hosted on a cloud account costing €81.45/month

Responsible:

Marco, because everyone else refused

Documentation:

a Notion page with one sentence and 14 empty headings
