Worked on the instabase/aihub-openapi repository to enhance API design and specification over a two-month period, focusing on secret management and data enrichment features. Migrated the Secret Management API to use JSON request bodies, standardized parameter naming, and updated OpenAPI specifications and example code, improving consistency and easing client integration. Later, expanded the /results API response to include detailed case information such as edit history, timestamps, and user IDs by updating the openapi.yaml schema. Leveraged YAML and OpenAPI Specification to deliver these features, laying a foundation for improved auditability, data quality, and smoother downstream integrations without introducing new bugs.
