What You're Going to Build

You application should be a server that’s able to do the following with a Postgres Database:

1. List All Patients in database via FHIR API
2. List All Observations in database via FHIR API
3. Get Patient Details in database via FHIR API
4. Get Observation Details in database via FHIR API
5. Must support JSON (and optionally XML) format

Best of luck!
