Java Developer for Healthcare Management System

I'm seeking an experienced Java developer to help build a reliable and intuitive web-based healthcare management system. The platform should, as a minimum, include functions for scheduling appointments and managing patient records. Spring Boot Role Base security needs to be incorporated for added system reliability and data privacy.

The ideal candidate would have:
- Strong experience in Java web development;
- Familiarity with e-commerce platform creation;
- Proficient in developing role-based security measures, especially with Spring Boot;
- Prior experience building healthcare management systems or similar.

This project requires someone who can capture and implement details effectively. Your understanding of my requirements will be reflected in the bid. Only serious and committed developers please. I'm looking forward to reviewing your proposal.
