HEALTHCARE
Custom healthcare software development
We build, integrate, and modernize HIPAA-compliant healthcare software — from EHR integrations to patient-facing apps — for hospitals, health systems, and digital-health companies.
WHAT WE BUILD
Custom healthcare software, built around real workflows
From integration to patient-facing apps, we deliver healthcare software built around how your clinical and operational teams actually work.
EHR & EMR integration (HL7/FHIR)
Connect and exchange data across EHR/EMR systems using HL7 and FHIR, so information moves cleanly between your systems.
Healthcare interoperability
Make disconnected systems talk to each other, securely, so data flows between providers, apps, and platforms without manual work.
Custom healthcare apps & platforms
Patient-facing and clinical applications designed around how your teams and patients actually work.
Telemedicine app development
Secure video visits, scheduling, and remote-care platforms your patients can use without training.
Remote patient monitoring & clinical decision support
Real-time monitoring, smart alerts, and ML-assisted insights that help clinicians act sooner.
Healthcare data & analytics
Pipelines, dashboards, and reporting that turn connected data into decisions.
INTEROPERABILITY
Healthcare interoperability
Most healthcare organizations don’t have a software problem so much as a connection problem: patient data trapped in systems that don’t talk to each other. Healthcare interoperability is what fixes that, and it’s core to what we do.
We build integrations on the standards your systems already speak — HL7 v2 and FHIR — and connect EHR/EMR platforms, labs, devices, and third-party apps through APIs and interface engines. Whether you need a single EHR integration or a hub that keeps dozens of systems in sync, we design for secure, reliable data exchange that holds up in production.
The result: clinicians see complete, current information; your teams stop re-keying data between systems; and new tools plug into your ecosystem instead of adding another silo. Better data flow means better decisions, fewer errors, and a foundation you can keep building on.
It’s the same engineering discipline behind our enterprise software development, legacy application modernization, and QA and testing.
INTEGRATIONS
Integrations we build on
We integrate on modern standards — FHIR R4 and HL7 v2 — and unified APIs like Redox and Health Gorilla, so your systems exchange data cleanly, whatever you run.
Don't see your system? We connect most platforms via FHIR R4 and HL7.
STANDARDS & COMPLIANCE
Built for HIPAA and compliance
Healthcare software has to protect patients as well as serve them. We build with HIPAA expectations in mind from day one — not bolted on at the end. That means encryption in transit and at rest, role-based access control, audit trails, and privacy-by-design across every workflow that touches protected health information. Your data, your patients’ trust, and your compliance posture are treated as non-negotiable.
We build FHIR-first, mapping legacy HL7 v2 feeds into clean FHIR resources, and design to current US interoperability rules.

Frequently asked questions
FAQ
Yes. We design for HIPAA from the first sprint, with encryption, role-based access, audit trails, and privacy by design. We’re also comfortable signing a BAA.
Yes. We connect EHR/EMR systems using HL7 and FHIR, with APIs and interface engines for secure, reliable data exchange.
Yes. We modernize aging platforms in steady, low-risk steps, so live operations keep running while we improve them.
Most engagements begin with a short scoping call about your goals, systems, and constraints. From there we recommend the smallest path to the outcome you want.
It depends on the scope and integrations. We scope projects based on the outcome, not the invoice, and only recommend what’s needed. Tell us what you’re trying to achieve, and we’ll give you an honest estimate.
