Enterprise Healthcare Test Data Management Platform

Full-stack, portfolio-grade Cloud Test Data Management platform for regulated healthcare (React/FastAPI/PySpark): PHI/PII discovery and deterministic masking with referential integrity across 5 heterogeneous systems, production-scale subsetting, synthetic data generation, an automated 12-gate certification pipeline, dataset lifecycle/refresh orchestration, storage/compute capacity planning, RBAC with real JWT authentication, and tamper-evident audit evidence packages. Built as an all-synthetic-data reference implementation with a 20-chapter tutorial and an honest, itemized security-limitations section.
