Doctor Appointment & Clinic Management App

I need a doctor appointment booking and clinic management application that supports iOS, Android, and Web.

Ideal skills for this project include:
- Cross-platform mobile and web app development
- UI/UX design
- Knowledge of healthcare software compliance
- Experience with appointment scheduling systems
- Understanding of patient management systems

Please provide examples of similar projects you've completed in your proposal.
