Seshadri Mahalingam
Seshadri Mahalingam enhanced the cube-js/cube repository by adding dataSource visibility to the /v1/sql API response, enabling clearer tracing of SQL query origins for analytics and business intelligence use cases. Working primarily with TypeScript and Node.js, Seshadri designed the feature to surface the dataSource field for both single and blended queries, supporting data governance without introducing breaking changes. The implementation included targeted tests to ensure reliable propagation of the new field, reflecting a test-driven approach and attention to backward compatibility. This work improved observability and provenance in the API, demonstrating thoughtful incremental delivery and solid API development practices.
