Specialized Engineering & Architecture for HealthTech. Specialized engineering and technical architecture for organizations handling PHI. We specialize in EHR integrations, HIPAA/SOC2 compliance, and secure local AI.

HEALTHTECH

  • Clinical Interoperability: HL7, FHIR, and custom EHR integrations. Interface engines between clinical systems; Proprietary EHR APIs alongside standard FHIR and HL7; A written data map before any sync ships
  • HIPAA & SOC2 Architecture: Cloud compliance, security assessments, and BAA management. Named PHI custody instead of a default cloud vault; BAAs when PHI is in scope; Security assessments and control mapping for the engagement
  • Medical AI & Local LLMs: Secure, local-first medical AI pipelines without exposing PHI. On-device or perimeter inference for clinical workloads; No default multi-tenant model API for regulated inputs; Evaluation scoped in writing
  • Claims & EDI Automation: Engineering data pipelines for healthcare claims and revenue cycles. 837 and 835 claim and remittance flows; Clearinghouse and payer interfaces; Reconciliation pipelines with a written scope

Government is a customer segment, not the brand

We respond to government RFPs, including through SAM.gov. Identifiers, NAICS, and the printable capability statement live on a dedicated procurement page.
