Worked on the TUM-Dev/NavigaTUM repository to enhance the accuracy of campus office location data, specifically updating FSEI office entries to reflect temporary relocations due to construction. Focused on data management using YAML, the work involved implementing a temporary override for affected office locations, ensuring that user-facing maps and search results displayed current and reliable information. The approach emphasized clear documentation and versioned changes, supporting ongoing data governance and repository maintenance. By surfacing updated entries in discovery flows, the project reduced user confusion and aligned with business goals of providing up-to-date campus information through disciplined data stewardship practices.
