Booking Management System

Built React and Node.js reservation flows with backend availability checks, staff administration, and automated reminders.

Two customers can choose the same slot before either completes a booking. A calendar view alone cannot confirm that the slot is still available when a reservation is submitted.

I connected customer booking flows to backend availability checks, staff administration, and reminders. The work covered creating, rescheduling, and cancelling reservations, with separate access for customers and staff.

• Booking changes

  Create, reschedule, and cancel reservations with availability checks.

• Resource scheduling

  Match services and resources to available time slots in calendar views.

• Staff administration

  Provide separate workflows for customers, staff, and administrators.

• Payments & reminders

  Connect payments with booking notifications and automated reminders.

I kept availability validation in the backend booking workflow. The calendar helps customers choose a slot, but the server checks the reservation request. The interface then needs to explain when a slot is no longer available and let the customer choose another.

Customers can manage their bookings, while staff track schedules and reservation status with automated reminders.
