You will get FHIR & HL7 EMR/EHR API Integration for your Healthcare Platform
Project details
I will connect your healthcare platform to any EMR or EHR system
using FHIR R4 or HL7 — Epic, Athenahealth, Kareo/Tebra,
eClinicalWorks, SimplePractice, DrChrono, Cerner, or AdvancedMD.
This is not a generic API integration. FHIR has its own OAuth flow
(SMART on FHIR), resource schema, and edge cases that break standard
REST implementations. I handle all of it.
What's delivered:
→ FHIR R4 or HL7 v2/v3 API connection fully configured
→ SMART on FHIR OAuth 2.0 authentication setup
→ Resource mapping — Patient, Encounter, Observation, Claim
→ Webhook or polling sync depending on your architecture
→ Error handling, retry logic, and failure alerting
→ HIPAA-compliant data handling and audit logging
→ Full technical documentation
Ideal for: health-tech startups, telehealth platforms, RCM
companies, mental health practices, dental groups, urgent care.

Job Success
Warrenton, United States - 8:20 am local time
I'm a backend developer and API integration specialist. My work sits at the intersection of healthcare software development, EMR integration, and workflow automation — the technical layer that keeps clinical and billing operations running without manual intervention.
Healthcare API & Interoperability
I build FHIR R4 and HL7 v2/v3 integrations that connect disparate healthcare systems — from Epic integration and Athenahealth integration to Kareo integration, eClinicalWorks integration, SimplePractice integration, DrChrono integration, and AdvancedMD integration. Whether you need a SMART on FHIR implementation, a CCD/CDA document pipeline, or a custom X12 EDI claims integration, I've worked with the standards that govern how healthcare data moves.
RCM Automation & Medical Billing Software
I build RCM automation systems that eliminate the manual steps between a completed visit and a paid claim. This includes claims submission automation, eligibility verification workflows, prior authorization automation, denial management pipelines, payment posting automation, and AR follow-up systems. If your practice is losing revenue to manual billing processes, I build the automation that closes that gap.
HIPAA-Compliant Application Development
Every application I build follows HIPAA compliance standards from day one — PHI encryption at rest and in transit, role-based access control, audit logging, automatic session timeouts, and secure BAA-covered infrastructure on AWS HIPAA-eligible services. I also build to SOC 2 and ONC standards when required.
What I build:
→ FHIR API integration with Epic, Athenahealth, Cerner, Kareo/Tebra, eClinicalWorks
→ HL7 interface development — ADT, ORU, ORM, MDM message types
→ Patient portal development — intake forms, scheduling, secure messaging
→ Telehealth application development — HIPAA-compliant video and messaging
→ Medical billing dashboards — AR aging, denial rates, collections analytics
→ EHR integration with third-party platforms via REST API and webhooks
→ Healthcare data pipelines — FHIR to database, reporting, Power BI
→ Insurance credentialing workflow automation
→ Benefits verification automation via payer APIs
→ Electronic health records custom development and integration
→ Revenue cycle management software and automation
→ Medical records software integration and migration
