About Me

I'm a Technical Architect specializing in healthcare interoperability, with deep expertise in HL7 FHIR, CDA, and cross-border healthcare data exchange.

Background

I work at the intersection of healthcare, standards, and practical software delivery. I'm a full-stack web developer working as a Technical Architect, based in Clane, Ireland. I enjoy coding and problem-solving, but most of all, I enjoy being part of a much bigger team.

My focus is on making complex interoperability problems understandable and building systems that work reliably in production. I work with the Health Service Executive (HSE) in Ireland, leading technical architecture for healthcare interoperability initiatives including Ireland's implementation of MyHealth@EU for cross-border patient data exchange.

Expertise

Healthcare Standards & Interoperability

• HL7 FHIR - Implementation, profiling, and governance across healthcare systems
• HL7 CDA - Clinical document architecture and transformation workflows
• MyHealth@EU - Cross-border healthcare data exchange and Patient Summary
• IHE Profiles - XDS, XCA, and other integration patterns
• Medical Imaging - DICOM, IHE XDS-I, and imaging interoperability

Technical Architecture

• API Design - RESTful APIs, governance, documentation, and developer experience
• Integration Platforms - Design and delivery of healthcare integration infrastructure
• Terminology Services - FHIR terminology servers, SNOMED CT, and clinical coding systems
• Medication Management - National medicinal product catalogues and ePrescription infrastructure
• Security Architecture - Healthcare data protection and privacy-preserving design
• Cloud Architecture - Azure-based healthcare solutions and modern deployment patterns

Software Development

• Python - Django, Django REST Framework, Flask
• Frontend - Angular, TypeScript, HTML, JavaScript
• Java - Healthcare integration servers and tools
• Data - PostgreSQL, MongoDB, data modeling for healthcare
• DevOps - Docker, CI/CD, containerization

Approach

I believe in:

• Standards-based solutions that enable interoperability
• Clear documentation that makes complex topics accessible
• Practical delivery over theoretical perfection
• Developer experience as a key success factor
• Security and privacy by design

Current Focus

My current work involves:

• Leading technical architecture for Ireland's MyHealth@EU implementation as part of the European Health Data Space (EHDS)
• Contributing to Xt-EHR (European Health Data Space project) across multiple work packages:
  • WP6.1: Patient Summaries towards EHDS
  • WP6.2: Electronic Prescriptions and Dispensations
  • WP7.1: Laboratory Results and Reports
  • WP7.2: Medical Imaging and Reports
• Establishing FHIR as the primary integration standard for HSE systems
• Designing API platforms and developer tools for healthcare integration
• Active participation in European healthcare interoperability working groups and standards development

MyHealth@EU: Cross-Border Healthcare in Europe

Leading the technical architecture for Ireland's National Contact Point (NCP) for eHealth, enabling secure cross-border exchange of healthcare data across the European Union. MyHealth@EU is the operational service supporting the European Health Data Space Regulation.

Current Services:

• Patient Summary - Essential medical information for treatment abroad
• ePrescription/eDispensation - Cross-border medication prescribing and dispensing

Future Services (in development with Xt-EHR):

• Laboratory results and reports
• Hospital discharge reports
• Medical images (X-rays, MRI, CT scans)

National Infrastructure & Standards

Contributing to Ireland's foundational interoperability infrastructure:

• National Medicinal Product Catalogue (NMPC) - Testing and evaluation of national medication management API using SNOMED CT terminology, supporting integrated medicine management across primary and secondary care
• Central Terminology Server (CTS) - Evaluation of FHIR terminology service providing SNOMED CT and Irish clinical reference sets for standardized clinical data representation

These services provide the foundational terminology and medication infrastructure that enables MyHealth@EU ePrescription services and FHIR-based integration across Irish healthcare systems.

Xt-EHR Project: Building EHDS Technical Specifications

The Xt-EHR project develops the technical specifications and implementation guides that services like MyHealth@EU implement. Contributing to multiple work packages developing FHIR-based standards for:

• Patient Summaries (WP6.1) - Core patient data for cross-border exchange
• Electronic Prescriptions & Dispensations (WP6.2) - Medication workflows and safety
• Laboratory Results (WP7.1) - Diagnostic test results using LOINC, NPU, and SNOMED CT
• Medical Imaging Reports (WP7.2) - Radiology reports using HL7 FHIR and DICOM standards

Certifications & Professional Development

Continuous learning in healthcare interoperability standards and technical architecture:

• openEHR & HL7 FHIR Technical Course - Better (openEHR & HL7 FHIR collaboration), May 2026

Standards Development & Working Groups

Active participation in European and international healthcare standards development:

• HL7 Europe - Medication Prescription and Dispense Working Group - Contributing to FHIR Implementation Guide development for European exchange format (EEHRxF) under EHDS Regulation, in collaboration with IHE and European projects (XpanDH, Xt-EHR, xShare, UNICOM)
• Xt-EHR Project Working Groups - Active contributor to WP6.1, 6.2, 7.1, and 7.2 technical specifications
• European eHealth Network - Technical representation in EHDS implementation discussions
• MyHealth@EU Community - Collaboration with Member States on cross-border data exchange
