I need a secure, web-based platform that lets our research group capture and organise data from ongoing clinical trials while safely storing large volumes of medical-imaging files. Three distinct roles will work inside the system—researchers, clinicians and technical assistants—so granular, role-based permissions and an audit trail are essential. Beyond the core data-collection workflow, the platform should also give us a public-facing area where we can: • showcase published results and selected images, • announce upcoming events, • list mentorship opportunities, and • manage paid or free subscriptions to that content. Upload tools must accept both structured eCRF entries and DICOM images, then index everything for quick search and export. I expect encrypted transmission (TLS 1.2+), at-rest encryption, and compliance with GDPR/HIPAA standards. A RESTful API, user-friendly React or Vue front-end, and a robust back-end such as Django or Node with PostgreSQL/MySQL will suit us well, but I am open to alternatives so long as documentation is thorough. Deliverables: • Source code in a private repo, commit history intact • Database schema and migration scripts • Deployment guide for Ubuntu-based servers (Docker preferred) • Admin/manuals covering user management, backups and updates • One-round hand-over session to verify installation and data flow Please rely on professional, human-written code only—no AI-generated modules or boilerplate.
