Worked on the teamg4it/g4it repository to implement digital service versioning and data traceability, focusing on backend development and database design. Updated input tables to support versioned data structures, enabling more robust data lineage and regulatory compliance. Enhanced the environmental footprint evaluation process to align with the new versioning approach, improving data accuracy and governance. Refined and expanded documentation using Markdown to clarify versioning and data management practices for the team. This work provided a foundation for faster incident resolution and better operational insights, emphasizing maintainable backend architecture and clear documentation without introducing major bug fixes during the development period.
