MediFlow
HIPAA-Compliant Healthcare API PlatformBackend Architect
/ The Brief
Healthcare teams deal with patient data that cannot afford to be mishandled. A breach is not just a technical failure; it carries legal consequences, and the architecture has to reflect that from day one.
/ The Solution
PHI encrypted at rest and in transit. Row-level access so providers only see their own patients. Automated audit trails on every access. Zero-trust network on AWS where nothing talks to anything it does not need to. FHIR-compatible data models so EHR integrations do not require custom connectors each time. Third-party HIPAA audit: passed on the first attempt.
