What made it hard

Constraints, and the response.

Every real system is shaped by what it had to work around. These are the constraints that drove the architecture.

01
Constraint

Appointment conflicts under concurrent booking

Response

Real-time availability checks with slot locking

02
Constraint

Accessibility for elderly, low-confidence users

Response

Large type, high contrast, and a deliberately shallow flow

03
Constraint

Integration with incumbent clinic-management software

Response

An API bridge to the existing clinic system, no data migration
