For the Canadian Patient Summary Jonathan is helping to implement the specification and updating profiles and implementation guide.

* Achieved the HL7 FHIR R4 Proficiency certification and trained on Smile’s Clinical Data Repository (CDR) application.* Worked with a team of architects to assess and design a solution that will enhance the Smile CDR implementation at Blue Cross Blue Shield North Carolina.* Proposed solutions for storage, updates and validation and contributed to security, ingestion and master data management (MDM) design.* Reviewed future requirements regarding CMS APIs (CMS-9115-F and CMS-0057-F) and established a path to support future Implementation Guides based on USCDI V3 and US Core 6.

* Created FHIR specifications for Provider, Location and Client Registries. Engaging with provincial stakeholders - eReferrals, document delivery, longitudinal record access.* Proposed a security model (Smart on Fhir and otherwise) for longitudinal record access interfaces with the health registries - client, provider and location - by working with BC Provincial Health Authority.* Built (as technical manager) the Provider Location Registry (PLR). The registry is a web-service-based system that manages provider data for the Province of BC. It is the central hub within an enterprise system that consumes secure web services from external organizations using an Enterprise Service Bus and produces notifications of provider changes, sent to connected parties. The system has a web interface developed on a JEE platform that is secured by KeyCloak/OAuth. It uses health level 7 XML (HL7v3) SOAP messages, FHIR and custom RESTful/JSON messages between exposed service interfaces.* Managed development teams as Scrum Master and filled the primary business analyst role for the Provider Location Registry.* Modelled systems using the Sparx Enterprise Architect tool and UML diagrams in a TOGAF framework.* Assisted a team of employees and contractors through contact negotiations and the first major milestone by defining tasks and schedule to deliver operational and application development services for the Health Integration Access Layer for the Ministry of Health eHealth strategy.* Upgraded the Practitioner Profiles architecture and design. The legacy system consisted of a 'rats nest' of tools, systems and manual interventions. The new system, besides incorporating Ministry standards for architecture, simplified the processes, saving time and money. A road map was also developed to include any future business intelligence tool opportunities.

* Contributed to the development of web and desktop software for radar interferometric image finishing. This included: managing requirements with customers and vendors, creating design and requirements documents, modifying system architecture and approving architecture decisions, building and managing a formal test process (which was previously lacking) and mentoring junior developers.* Created the following desktop applications:** TapeArchive is desktop application to transfer raw radar data at high speeds from a JBOD (just a bunch of disks) to Ultrium tapes;** TapeUnload is a console application to backup, from a RAID to Ultrium tapes;and the IES AutoProcessor which is a desktop application that detects database changes, starts an external process and updates the database to automate some process management tasks.

*Developed and implemented algorithms for GPS wide area augmentation system in Europe used for en route aircraft navigation and GPS signal monitoring*Led a small team in desktop application development to track GPS signal interference levels.*Developed a GPS timing simulator for real-time embedded firmware and built components for an automated test suite.
