EHR / EMR Middleware

Engineering Approach

Siloed data is the enemy of operational velocity. We specialize in building secure, highly scalable middleware translation layers that allow your custom consumer-facing applications to read and write data directly into enterprise monoliths like Epic, Cerner, and Athenahealth without breaking compliance or overwhelming their APIs. Most healthcare IT departments treat their EHR as a fortress: locked down, slow to change, and hostile to third-party integrations. If you're building a patient-facing mobile app, a provider scheduling tool, or a clinical decision support dashboard, getting real-time access to EHR data is the hardest part of the project. The EHR vendors offer APIs — FHIR for modern systems, HL7 v2 for legacy — but these APIs are rate-limited, poorly documented, and require hospital-specific security approvals that take months. Worse, if your clinic network uses multiple EHR systems (some locations on Epic, others on Cerner or Athena), you're forced to build and maintain separate integrations for each vendor. This is where middleware becomes essential. A well-architected middleware layer sits between your application and the EHR, translating vendor-specific API calls into a unified internal interface. Your app makes one request — the middleware handles Epic's SMART on FHIR flow, Cerner's OAuth nuances, and Athena's proprietary MoreDisruptiveAPI behind the scenes. The middleware also absorbs the EHR's rate limits, queues failed requests with exponential backoff retry logic, and caches frequently accessed data to reduce API load. For hospital IT teams, this reduces risk — they grant your middleware limited, scoped API access once, and your application never touches the EHR directly. For your engineering team, this means faster feature development, fewer vendor-specific bugs, and the ability to onboard new EHR vendors without rewriting your core application logic.
