Hospital EHR System with App and Website

I'm looking for a EHR system for a hospital, complete with an app and website. The backend should be robust and secure.

Essential functionalities include:
- Patient management
- Access control
- Bed and room assignment

The app should be developed for both iOS and Android platforms. I have some design ideas but need assistance in finalizing them.

Ideal candidates should have:
- Proven experience in developing EHR systems
- Strong background in mobile and web app development
- Knowledge of healthcare regulations and security standards
- UI/UX design skills to help refine my ideas

Please provide a portfolio demonstrating relevant experience.
