Worked on the GeoscienceAustralia/dea-config repository to deliver a new ESA Sentinel 2C Level 1 product definition, focusing on enhancing data discoverability and interoperability for geospatial workflows. Developed a well-structured metadata schema using YAML, aligning the product definition with the eo3_sentinel metadata standard to ensure consistent ingestion and cataloging of S2C Level 1 data. Applied configuration management and data modeling skills to define product attributes such as name, description, license, and spectral band details. This work improved downstream workflow reliability by providing a standardized schema, supporting more robust data integration and enabling easier access to Sentinel 2C Level 1 datasets.
