Doctor Appointment Scheduling System

I'm looking for a talented developer to create a comprehensive doctor appointment scheduling system that works on both a website and a mobile app for both iOS and Android platforms.

The system should include:

- Booking appointments: A user-friendly interface for patients to book their appointments easily.

- Sending reminders: Automatic reminders for upcoming appointments to reduce no-shows.

- Patient record management: A secure and efficient system for managing patient records.

- Doctor schedule management: Allow doctors to set their availability and manage their schedule.

- Multi-language support: Provide translations for different languages to cater to a diverse patient base.

- Payment integration: Facilitate online payments and transactions for appointments.

- Telehealth integration: Include video consultation features for remote appointments.

- Review system: Allow patients to leave reviews and ratings for doctors.

- Notifications: Provide notifications for appointment confirmation, cancellations, and updates.

- Search/filter functionality: Enable patients to search and filter doctors by specialty, location, and available dates.

- Appointment history: Allow patients to view their past and upcoming appointment history.

- User authentication: Implement secure login and registration for both patients and doctors.

- In-app chat: Facilitate direct communication between doctors and patients through in-app messaging.

Ideal candidates for this project should possess:

- Proven experience in developing cross-platform applications.

- A strong understanding of patient record management systems.

- Excellent skills in implementing reminder systems.

If you have the required experience and skills, please bid on this project.

The system must integrate with existing hospital or clinic systems. The development should be done using Flutter for the mobile app. The design should be modern and vibrant, making the app visually engaging.
