A production-shaped booking system for a single football pitch, built Arabic-first with a right-to-left interface.
Players open the site, see which half-hour slots are free, and book one with a name and a phone number — no account, no online payment, cash on arrival. Staff sign in to a separate dashboard to see the day's schedule, record walk-in bookings, close hours for maintenance, set the hourly rate and working hours, and manage each other's accounts.
The interesting part isn't the CRUD — it's that a football pitch is open around the clock, so a booking from 11 p.m. to 1 a.m. is ordinary rather than exotic. That single fact shapes the whole data model.
