Daniel, a key account manager

Build time:

2 hours 37 minutes

Built with:

Google Apps Script

Database:

a REST API backed by another REST API backed by Excel

Authentication:

the encryption key is in a comment explaining not to share it

Deployment:

hosted on Sarah's personal Vercel account

Responsible:

an agency acquired by another agency

Documentation:

a Loom video whose owner account has been deleted

Security situation:

it has an admin panel, unlinked, unprotected

Future disaster:

It will cause Security to ask "what application?".

Age: 28 days · originally expected to last 2 months · 2 owners so far · survived 1 reorganisation · last meaningful change 3 days ago · original builder left 59 days ago

Rated common mostly because: 2 accidental connections, nobody owns it, the builder has left.
