Our hospital-management platform is already running on Django and Django Rest Framework; the next milestone is full HL7 FHIR compliance. I need new endpoints and model work that cover patient management, appointment scheduling, medical-records access, inpatient and outpatient (OPD/IPD) flows, radiology & imaging, and billing—all exposed through a clean DRF API. The job touches every layer of Django: designing or refactoring models and database schema to mirror FHIR resources, wiring serializers and views for RESTful operations, and building or adjusting the HTML templates, forms, and server-side validation that staff will use day to day. A complete OpenAPI/Swagger schema should accompany the code so downstream systems can integrate without guesswork. Deliverables • Django models aligned with relevant FHIR resources, with migrations • DRF serializers, viewsets, URL routing, authentication & permission rules • Functional templates and forms for administrative and clinical staff workflows • Swagger / ReDoc documentation auto-generated from the codebase • Brief setup guide plus test data demonstrating each endpoint Have good knowledge on health care systems and experienced python developer Acceptance criteria: endpoints respond with valid FHIR-formatted JSON, unit tests pass, and the documentation renders without errors. Code must be clean, well-commented Python 3.x and ready to drop into our existing Git repository.
