Golrokh Mehran extended the Hivemapper/odc-api repository by adding calibration attribute support to the FrameKm metadata, focusing on enhancing data quality and interoperability for downstream analytics. She implemented new calibration fields such as calibM2, calibD2, calibRRgb, and focal length parameters, ensuring these attributes are included during metadata packing and upload processes. Her work enabled server-side calibration data uploads and supported overrides for mf_attributes, maintaining alignment with existing workflows and repository standards. Using TypeScript and leveraging skills in API and backend development as well as database management, she delivered a targeted feature with depth and careful integration into the codebase.
