Worked on the osmlab/name-suggestion-index repository to enhance data quality by addressing inaccuracies in the regional representation of Muji stores. Focused on data curation, the developer identified and resolved a bug in department_store.json, ensuring that Muji locations are correctly classified across different regions. This targeted fix, implemented through a single, traceable commit, improved the integrity and consistency of the dataset, which is essential for accurate storefront mapping and analytics. The work relied on proficiency with JSON and data management practices, emphasizing careful validation and accountability in the update process to support downstream data reliability for users of the repository.
