Scheduling system

Online booking and reminders for a small clinic that was losing one in five appointments to no-shows.

Client: A two-chair dental clinic (fictional)
Year: 2024
Role: Design, Full-stack engineering
Stack: Next.js, PostgreSQL, Twilio, Resend

Placeholder case study: a fictional brief that shows the layout until real work replaces it.

Context

The clinic booked by phone and reminded nobody. Patients forgot, chairs sat empty, and the receptionist spent her mornings calling the afternoon list.

Idea

A booking flow that fits on one screen, built on the clinic’s real constraints (two chairs, procedure durations, one hygienist on Tuesdays), with reminders by SMS two days and two hours before.

Craft

Availability is computed from chairs and staff, not from a calendar someone has to maintain.

Reminders carry a one-tap confirm or reschedule; the schedule updates itself.

The front desk view is a single day, drawn to scale, printable.

Outcome

Shipped on Next.js and Postgres with Twilio reminders.
