Doctor/Lab Appointment App

I am looking for a talented developer to create an appointment scheduling app for Doctors and Labs which will run on an Android platform. This app will have the standard features for appointment scheduling such as appointment scheduling, reminders, Lab test home sample collection and the ability to save contact information. Authentication for users will be done through email and password or otp. The goal is to have a user-friendly, secure, and reliable app that medical professionals and patients feel safe using. The desired developer should have knowledge and experience developing with mobile applications and user authentication. I am open to any suggestions that the developer may have to improve the project. Also, developer who have worked on similar project needs to contact me.
