For 2025-03, the 13_odis work focused on data extraction standardization, ELT governance, expanded analytics coverage, and repository hygiene to improve data reliability, scalability, and business value. Key outcomes include: standardized data retrieval via JsonApiExtractor and updated communes data; comprehensive ELT documentation; a new dbt-based Silver Layer (bronze/silver/gold) with data quality tests and integration of new geo-data sources; addition of mobility, employment, and INSEE data; and consolidation/cleanup of seeds, imports, logs and obsolete workflows to streamline CI/CD. A controlled rollback was executed for the Silver Layer to stabilize the pipeline. Business impact includes improved data quality, broader analytics capabilities, and reduced operational risk through better governance and maintainability. Technologies demonstrated include JsonApiExtractor (Python), dbt, ELT architecture, data modeling, and cross-source data integration; collaboration evidenced by co-authored contributions.
