Healthcare practices and health-tech companies hire me when they need FHIR integration, HL7 integration, or HIPAA-compliant backend development done right the first 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 EMR & Billing Platforms I work with: Epic · Athenahealth · Oracle Cerner · Kareo/Tebra · eClinicalWorks · SimplePractice · DrChrono · AdvancedMD · Office Ally · CollaborateMD · Practice Fusion · Medisoft · CareCloud · NextGen · Allscripts Technical Stack: Backend: Node.js · Python · PHP · Laravel · REST APIs · GraphQL · Webhooks Healthcare: FHIR R4 · HL7 v2/v3 · X12 EDI · SMART on FHIR · CCD · CDA · DICOM Cloud: AWS · Google Cloud · Docker · Kubernetes · Vercel · GitHub Database: MySQL · MongoDB · PostgreSQL Frontend: React · Next.js · Tailwind CSS · JavaScript Specialties by practice type: Mental health practices · Dental billing · Hospice software · Chronic care management · Urgent care · Cardiology · Multispecialty groups · Telehealth platforms · Health-tech startups · RCM companies I work with solo providers, multispecialty groups, RCM companies, and health-tech startups.
