Samuel Ketels enhanced the MewsSystems/gitbook-connector-api by extending its identity document schema to support Spanish Identity Documents. He introduced the IdentityDocumentSupportNumber field to both request and response schemas, enabling more comprehensive data capture and improved eligibility checks in compliance with Spanish regulations. Samuel focused on clear documentation and commit-based change tracking, ensuring traceability and maintainability throughout the process. Working primarily with Markdown for documentation and JSON schema for API design, he delivered a targeted feature that improved onboarding workflows for Spanish IDs. The work demonstrated depth in schema evolution and careful attention to regulatory requirements, with no bugs reported.
