Web design UI/UX Web & Mobile app for medical/healthcare records storage & sync

My project is to design a mobile app to store and sync medical records. It will be used by both doctors and patients, and support platforms iOS, Android, & Web. The app will provide a secure data repository to ensure the safety and privacy of confidential information, and feature an easy-to-use web & mobile experience tailored to the particular needs of medical professionals and patients. To provide intuitive navigation, the app should leverage UI/UX design principles that are optimized for use on desktop, mobile, and tablet devices. The app will condense the user experience so that important information can be quickly accessed, and clinical decisions can be quickly made. All medical data stored in the app must be secure and synced with other medical apps, allowing relevant team members to access records electronically.
PS: It has to be in Portuguese.
