Healthcare's Hidden Curriculum: Production Reliability Lessons from FHIR Backends

This article reframes 15 production incidents as valuable learning experiences in healthcare backend development, revealing why FHIR systems demand stricter engineering discipline than typical consumer applications. Healthcare incidents directly impact patient care—from medication approvals to regulatory compliance—creating an environment where robust practices become non-negotiable. The author shares concrete technical solutions (schema validation, idempotency design) that showcase how healthcare's high stakes force engineers to adopt reliability practices applicable to any production system.
