The problem
Patients waited in crowded rooms for hours because nobody knew when their turn would come.
Constraints
- Front-desk staff had five minutes of training time.
- Patients only reliably have SMS, not smartphones.
Architecture
- React front desk
- Express API
- Postgres
- Twilio SMS
Key decisions
SMS over a web app for patients. Every patient could receive a text; far fewer would open a link.

What I'd do differently
Measure wait times before launch, so the improvement could be proven rather than estimated.
