Worked on the EOSCogniton/ELIZ-2022 repository to update SES workbook documentation for the 2025 data set, focusing on enhancing data accessibility and governance. The effort involved editing and restructuring the FS25_SES_v1_EPSA.xlsx workbook using Excel and data modeling skills, adding new sections such as T3.13, T3.5, FBH, and Spt Structure to support evolving requirements. Maintained a detailed change history through multiple Git commits, ensuring traceability and rollback capability. The updated documentation improved readiness for the 2025 SES deployment, streamlining onboarding and compliance reporting. No bug fixes were recorded during this period, with work centered on documentation and structure.
