Case study / WaitOnce

From founder's idea to a live healthcare platform.

Coding Diver's director, Aaqib Kitab, served as acting CTO for WaitOnce, an Australian platform that fills cancelled allied health appointments from the clinic's waitlist. He architected the whole application, its integrations with leading practice management systems, the member and admin portals and the mobile app, and had it live within the client's timeframe.

The story

Turning a clinician's insight into a working product.

WaitOnce was founded by an experienced allied health professional who saw the same problem every day: clinics lose revenue to cancellations while clients wait months for an appointment. The founder needed a technical leader to turn that insight into a product.

The Challenge

WaitOnce had a clear idea and a firm deadline, but no technology team. The platform had to connect to the different practice management systems clinics already use, serve clinics, clients and administrators in different ways, and handle complex scheduling: variable session lengths, recurring appointments and families with several children in care.

The System

As contractual CTO, Aaqib designed the end-to-end architecture and formulated how every part works together. WaitOnce integrates with practice management systems including Cliniko, Halaxy, Nookal and Splose, so cancellations and bookings sync with each clinic's existing diary. A permissions-based model lets each clinic control what every client can see and book.

The Solution

Coding Diver delivered three connected products. A member portal and mobile app let clients see bookings across multiple providers, get notified of earlier appointments and accept cancellation offers in seconds. An admin portal gives the WaitOnce team control of clinics, subscriptions and activity. The platform launched within the client's timeframe.

Outcomes
