I’m ready to turn my concept for a patient-data management app into a fully functional healthcare solution. The core goal is to streamline how clinics and hospitals capture, store, and retrieve patient information while keeping every record secure and compliant with industry standards. Here’s what I’m looking for you to handle from end to end: • Design an intuitive, multilingual interface that makes registration, charting, and record lookup effortless for medical staff. • Build a scalable backend—cloud, on-prem, or hybrid—capable of handling thousands of concurrent records without lag. • Implement robust data-security measures (role-based access, AES-256 at rest, SSL/TLS in transit, audit trails) so we meet local health-data regulations. • Provide RESTful APIs for interoperability with existing hospital information systems, lab platforms, and future mobile extensions. • Supply concise technical documentation and a test suite (unit + integration) so maintenance and future enhancements are straightforward. Acceptance criteria 1. All CRUD operations for patient demographics, encounters, lab results, and imaging data complete in ≤300 ms under a simulated load of 500 users. 2. OWASP Top 10 vulnerability scan returns no critical issues. 3. Codebase passes automated tests with ≥90 % coverage and compiles without warnings. 4. End-user walkthrough video and admin guide delivered alongside source code and deployment scripts. Stack is flexible—Node.js, Python (Django/FastAPI), Java (Spring), or a framework you can justify—but the final product must run on Linux and use PostgreSQL or another ACID-compliant database. If you’ve built EMRs, EHR integrations, or HIPAA-grade apps before, let’s discuss how you’d approach architecture, timeline, and milestones.
