Worked on the Amsterdam/amsterdam-schema repository to enhance the data schema for waste collection points, focusing on improving data quality and governance. Introduced new fields to uniquely identify shopping areas, enabling more precise categorization and filtering for operational analytics. Addressed a version control issue by reverting an incorrect dataset update, ensuring accurate versioning and traceability across releases. Applied skills in data management, schema design, and version control, working primarily with JSON to maintain dataset integrity. The approach emphasized clear documentation and commit practices, supporting reliable downstream analytics and better usability for planning and operations within the waste management domain.
