Afreen developed the FHIR Data Ingestion API and cache persistence layer for the OHDSI/Data2Evidence repository, focusing on enabling robust end-to-end data flow for healthcare resources. She introduced new API endpoints using TypeScript and JavaScript, allowing users to create projects and ingest FHIR resources efficiently. Her work included implementing subscription-based triggers to automate downstream data processing and integrating a cache-backed database layer to ensure the durability and availability of ingested data. By updating the FHIR data model and leveraging Docker for deployment, Afreen delivered a technically sound solution that addressed both data persistence and workflow automation within a microservices architecture.
