Senior Software Engineer at Document Storage Systems who developed Juno Health EHR ordering and pharmacy systems.

At Document Storage Systems Inc., I designed and implemented Order Management and Computerized Provider Order Entry for the Juno Health EHR system, serving acute care and mental health facilities. I also developed JunoRx, including its pharmacy inventory module and medication interaction checks.

I connected healthcare systems through FHIR-compliant architecture and HL7 interfaces, and used RabbitMQ for event messaging. My work also included barcode label printing and PowerBI datasets.

Previously, at CUSHMAN & WAKEFIELD, I designed and implemented the JobCenter Appraisal Management system and developed property data APIs and mobile applications. Across my roles, I've built software for healthcare, commercial real estate, security, and other domains.
