Healthcare-IT integration and record matching, engineered to last.

SYSNET International is a woman-owned software-engineering firm that has helped government and private clients connect their systems and clean up their data since 1998 — including the HL7 integration behind the VA's MyHealtheVet patient portal, and our own record-matching product, OpenEMPI.

What we do

Three decades of building and integrating mission-critical systems — with deep roots in healthcare information technology.

Healthcare IT integration

HL7 interfaces, health-information exchange, and patient-data workflows — the work behind the VA MyHealtheVet Personal Health Record portal.

Record matching & entity resolution

Deduplicate and link records across systems with our product OpenEMPI — an enterprise master patient/entity index used in healthcare and beyond.

Custom software engineering

Full-lifecycle development for government and private clients: requirements, architecture, implementation, testing, and performance tuning.

Our flagship product

OpenEMPI — enterprise record matching

OpenEMPI is SYSNET's master patient/entity index: it deduplicates and links records across disparate systems so organizations can work from one source of truth. Born in healthcare, it now powers entity resolution across many domains.
