Roger Panayfo

Healthcare IT and radiology systems professional with 12+ years of experience supporting RIS/PACS environments, DICOM/DMWL workflows, HL7 v2 interoperability, Oracle/SQL databases, Windows/Linux systems, production incidents, customer communication, and technical documentation. Experienced in hospital/radiology workflows involving patient registration, scheduling, orders, exams, reports, modality worklists, image availability, PACS services, and clinical continuity. Strong background working with customers, hospital IT contacts, vendors, support teams, development teams, and project stakeholders.

Although my formal titles have been support engineer and Java RIS developer, my experience is strongly aligned with Field Service work: remote support, technical evidence gathering, escalations, implementation-adjacent project activities, data migrations, troubleshooting, documentation, and support for healthcare production environments.
