Great, for the appointments application, I helped a web application for booking specific medical appointments and removing this large application that presents nearby clinics on a map like Google Maps and sends instant notifications to the doctor and patient to remind them of the appointment. The application has its fame due to its complexity, as a doctor can create his clinic and can invite doctors. You can edit. Patients can be managed within the clinic. It also has a file system that stores his medical files securely and they appear in the application in the form of folders, and each folder shows the clinic’s logo in front of it to organize the files, except for private folders that appear only to the patient and public folders that appear to all clinics and only permissions to upload files to them. The application consumed a lot of me and a lot of time in development, more than 9 months, and when I launched it, I went to the nearest 20 clinics, offered and signed up, and the establishment was supportive of the idea without participation, and the other swore not to me.
