Worked on the icanbwell/fhir-server repository to streamline the GraphQL server configuration by removing subgraph-related functionality and simplifying the overall setup. The approach involved eliminating the use of buildSubgraphSchema, relocating the scalar_type definition into FhirProperty to better align with the data model, and cleaning up unused dependencies and dead code. This backend development effort, using JavaScript and Python, resulted in a more maintainable and reliable GraphQL server configuration. The changes reduced system complexity and maintenance overhead, ensuring that future updates can be implemented more efficiently while maintaining alignment with evolving project requirements and technical standards.
