Worked on the Kvgr98/Modular repository to deliver targeted data management enhancements over a two-month period. Focused on updating and enriching the Roteiro.csv dataset, the work included adding new route entries and process documentation to support clearer route planning and improved workflow integration for JATEAMENTO. Leveraging CSV as the primary data format, the developer introduced new identifiers and codes to facilitate downstream analytics and reporting, while ensuring no changes to application logic. All updates were committed as data-only uploads, maintaining codebase integrity. The approach emphasized structured data enrichment and process clarity, supporting compliance and readiness for future reporting cycles.
