Low-Code Appointment Booking System for Clinic Network Using Flutter

Low-Code Appointment Booking System for Clinic Network Using Flutter

A growing multi-clinic healthcare network based in Lisbon, Portugal, wanted to modernize patient scheduling with minimal engineering investment. Their legacy system worked manually—front-desk teams managed appointments through calls, spreadsheets, and physical logs, leading to delays and misaligned queues. The organization partnered with our engineering team to build a low-code appointment booking application using Flutter-based visual components and modular workflows.
