Kakou worked on the takamatsu-city/opendata repository, delivering foundational data assets and refining localization to support data-driven location features. They created and committed data.csv and data.xlsx files containing sandbag creation location data, enabling reference-based location selection and laying groundwork for future workflow enhancements. Kakou also addressed a localization issue by correcting a Japanese configuration label in YAML, ensuring UI consistency without altering functionality. Their approach emphasized clear documentation, commit hygiene, and repository readiness, demonstrating solid configuration management skills. The work, though limited in scope, was methodical and positioned the project for maintainability and further data-driven development using YAML.
