IT Services and IT Consulting Columbia, MD 501–1,000 employees Founded 1999 Privately Held

FEI Systems builds healthcare software for government agencies — behavioral health systems, long-term care platforms, and clinical applications. The stack is Microsoft-centric (.NET, C#, SQL Server, Azure DevOps) paired with AWS Lambda, suggesting a hybrid cloud posture for federal compliance. Active projects reveal a compliance-first engineering culture: NIST RMF implementation, SOC 2 Type 2 audit readiness, and domain-driven design adoption sit alongside technical debt and system maintainability challenges — typical of mature government software managing complex interdependencies.
