Vijendra worked on the UKHO/Shop-Facade repository, focusing on modernizing its API by introducing versioning and refining the OpenAPI specification. He implemented API versioning by prepending a version identifier to endpoints, enabling stable and incremental evolution of the service. Using YAML and leveraging skills in API design and OpenAPI Specification, Vijendra refactored the API spec to extract shared components for headers and responses, reducing duplication and improving maintainability. He also simplified the getUserPermitsResponse schema to better align documentation with actual payloads, which streamlines client integration. The work emphasized maintainability and future-proofing over breadth, with no bugs reported.
