Challenge
Every EHR implements FHIR differently.
Agnotic approach
We build against each EHR's real FHIR capability statement, not the base spec, and abstract the differences.
FHIR / SMART on FHIR
FHIR / SMART on FHIR Development
We build real healthcare interoperability — FHIR R4 APIs, SMART on FHIR apps that launch inside the EHR, and clinical data exchange — engineered against US Core and the OAuth 2.0 launch framework, not a happy-path demo.

What FHIR / SMART on FHIR development involves
FHIR is the modern standard for healthcare data, and SMART on FHIR is how apps launch securely inside an EHR with the right patient and user context. Together they let you build apps that read and write clinical data — Patient, Observation, Condition, MedicationRequest — through a standard API instead of bespoke per-vendor interfaces.
The hard part is the real ecosystem, not the spec. Every EHR implements FHIR slightly differently, the OAuth 2.0 launch and scopes have to be exact, and US Core profiles constrain the data. We build FHIR apps and APIs that handle that variance, pass EHR app-gallery review, and stay compliant end to end.
Architecture
See how we design FHIR apps and APIs — SMART launch, OAuth 2.0 scopes, US Core profiles, and multi-EHR connectivity.
Common failure modes
FHIR pitfalls — and how we handle them
Challenge
SMART launch and OAuth scopes are easy to get wrong.
Agnotic approach
We implement the SMART App Launch framework precisely — EHR and standalone launch, scopes, and token handling.
Challenge
US Core profiles constrain the data.
Agnotic approach
We validate against US Core so resources satisfy downstream conformance and app-review requirements.
Challenge
App-gallery review stalls go-live.
Agnotic approach
We plan Epic/Cerner marketplace review into the schedule so it doesn't surprise the launch.
FHIR / SMART on FHIR Capabilities
The exact interoperability surface behind production FHIR apps.
FHIR R4 APIs
Read and write FHIR resources against EHR and cloud FHIR stores with correct profiles.
SMART App Launch
EHR and standalone launch with OAuth 2.0 scopes, context, and token handling.
US Core & profiles
Conformant resources validated against US Core and implementation guides.
Data exchange & mapping
Bulk data, subscriptions, and HL7 v2/C-CDA to FHIR transformation.
Where it runs
FHIR workflows we build
EHR-embedded apps
SMART on FHIR apps that launch inside Epic, Cerner, and others.
Patient-facing apps
Standalone apps that connect to patient FHIR data with consent.
Clinical data exchange
Read/write clinical data across systems via FHIR APIs.
Data onboarding
Bulk FHIR and HL7-to-FHIR transformation to seed a platform.
Analytics ingestion
Normalize clinical data into FHIR for population analytics.
Interop middleware
A FHIR facade over legacy systems for modern consumers.
FHIR that survives real EHRs
FHIR projects break on EHR variance and OAuth, not the resource model. We plan for the ecosystem from day one.

Frequently Asked Questions
A focused SMART on FHIR app typically ships in 2–4 months, depending on how many EHRs are targeted and whether app-gallery review is required. EHR variance and the review process drive the timeline more than the FHIR model, so we scope against your target EHRs from the start.
