Healthcare Imaging Platform Architecture Blueprint

I am seeking an experienced Software Architect to define and design a secure, scalable architecture for a healthcare imaging platform. The solution will include modules for high-volume medical image upload and storage (including DICOM format), an advanced image viewer for radiologists with navigation and visualization capabilities, and a structured case management workflow covering case creation, assignment, reporting, and closure. The system must incorporate role-based access control, secure authentication, comprehensive data encryption (both at rest and in transit), and adhere to regulatory frameworks such as HIPAA and GDPR. Prior experience in healthcare technology or enterprise-grade imaging systems will be considered a significant asset.
