You will get a secure FHIR API integration for your healthcare application
Project details
Need to connect your healthcare application to a FHIR-compatible server or EHR?
I will review, design, or implement a reliable FHIR API integration using ASP.NET Core and C#. Depending on your selected package, the project can include:
• FHIR resource mapping and transformation
• SMART on FHIR or OAuth 2.0 authentication
• Patient, Practitioner, Appointment, Encounter, or Observation resources
• Validation, error handling, and logging
• API testing and troubleshooting
• Source code and technical documentation
With 5+ years of development experience and a 100% Upwork Job Success Score, I focus on clean architecture, maintainable code, clear communication, and dependable delivery.
Each package covers a defined number of FHIR resources. Vendor licensing, production credentials, UI development, compliance certification, and HL7 v2 interfaces are not included unless agreed separately.
Please connect me before ordering if your integration involves multiple EHR vendors or more than three FHIR resources. Only synthetic or test patient data should be provided.

I focus on understanding the business problem before recommending a technical solution. My goal is to deliver software that works reliably today and remains maintainable as your product grows.

I’ll review the requirements and suggest the most practical next step.
