About the client

CHALLENGE

Design challenges to solve

Four design challenges that transform both the patient experience and reception work.

Designed not as a mere booking app, but as a healthcare platform that simultaneously automates reception work and lets doctors prepare in advance.

Morning phone bookings surge and overwhelm reception

Per locationHundreds of booking calls concentrated in a few morning hours, so reception staff cannot get on with other work.

Paper cards must be carried every time and are easily lost

Issued under a different number per location →For a whole family, that’s several to a dozen-plus cards, and reissue costs pile up whenever a card is lost.

Handwritten questionnaires stop doctors from reviewing in advance

Fill in after arrival → nurse reads it → hands it to the doctora time lag leaves pre-consultation prep insufficient.

Managing bookings for the whole family is cumbersome

Separate parent / child accounts had to be created and switched between, Hard to combine pediatrics and internal-medicine bookings on the same day。

ARCHITECTURE

The architecture we built together

From booking to the digital patient card — four domains unified in one app.

Simultaneous iOS / Android development with React Native (Expo) + Redux Toolkit + React Query; delivery to 4 environments (dev/stg/pre-prod/prod) automated via EAS Build. Firebase FCM pushes instant booking reminders and consultation-call alerts.
