PROFILE

Hyunseung Park

Worked on the osmlab/name-suggestion-index repository to enhance Korean public transportation data by integrating Wikidata values, expanding train and subway routes, and improving operator tagging for both transit and toll datasets. Applied data engineering and JavaScript skills to enrich route and stop information, correct operator metadata, and update payment options for toll operators, resulting in more accurate and comprehensive datasets. Focused on JSON handling and data validation to ensure schema simplicity and prevent placeholder data. These targeted improvements increased data reliability and search relevance for downstream mapping applications, supporting internationalization and localization needs for Korean transport systems.

October 2025: Delivered two focused changes in the osmlab/name-suggestion-index repository to enhance data quality and usefulness for Korean bus information. Key feature: Wikidata enrichment for Korean bus network to enrich routes and stops with external knowledge, improving data completeness and search results (commit 19ce7c4a1a6a16175d821e5a74205839d0ee3b73). Key fix: removed an unused empty 'note' field to simplify the data schema and prevent placeholder data (commit 618f0399c326827d1e77538f1dc91ddd905ba75a). Impact: higher data quality, better searchability, and smoother downstream processing. Demonstrated skills: Wikidata integration, data cleaning, schema simplification, Git-based collaboration, and delivery against performance goals.
