Worked on the basedosdados/queries-basedosdados repository to deliver a comprehensive documentation overhaul focused on improving onboarding and collaboration. Modernized the README to provide a clear overview of data pipelines and included structured contribution guidelines to clarify environment setup, data upload, and dbt-based model development workflows. Emphasized maintainability by detailing processes and expectations for both contributors and users. Utilized Markdown for documentation and leveraged data engineering concepts alongside dbt to ensure technical accuracy. The work established a foundation for streamlined contributions and easier project adoption, reflecting a methodical approach to documentation and process clarity rather than direct feature or bug development.
