Summary
👤
Senior🎓
Top SchoolKevin Mayfield is an Enterprise Integration Architect with 11+ years focused on health informatics, specialising in NHS interoperability, HL7 FHIR and IHE profiles across regional and national services. He has delivered end-to-end integrations for genomics, laboratory workflows, document sharing, electronic prescribing and COVID vaccination certification, bridging primary care systems, national services (PDS, MESH, NRLS) and patient-held records like Apple HealthKit. Comfortable both as an architect and hands-on developer, Kevin has built FHIR adaptors, validation tooling and demonstration apps, and led migrations and complex data transformations for Defence and NHS programmes. His work emphasizes pragmatic, patient-centred workflow design (FHIR Workflow, Structured Data Capture, Dynamic Care Planning) rather than purely technical specifications. Based in Leeds, he combines deep knowledge of SNOMED, dm+d, NHS data dictionaries and openEHR with practical cloud deployments (AWS FHIRWorks). An early career in primary care systems and data migration gives him rare end-to-end insight from legacy ETL to modern API-first interoperability.
