Andrey Orst developed Apollo Federation support for the Aidbox/examples repository, enabling federated queries across multiple GraphQL services within the Aidbox FHIR GraphQL API. He implemented a GraphQL gateway and designed a Docker Compose setup to streamline both local development and deployment, focusing on reproducibility and ease of onboarding. His work included updating documentation to provide clear federation setup instructions, usage guidelines, and example configurations. Using JavaScript, YAML, Apollo, and Docker, Andrey delivered a cohesive solution that allows teams to compose multiple APIs into a unified schema. The work demonstrated depth in full stack development and modern API architecture.
