Johan Schuijt enhanced the opensanctions/opensanctions repository by developing a new data extraction feature focused on the Dutch House of Representatives. He built a Python-based web scraper to collect member names and profile links, then enriched the dataset by crawling individual pages for metadata such as birth dates and birthplaces. Johan implemented robust date parsing and occupancy calculations, introducing a position entity to track active periods for each member. Leveraging skills in data engineering, web scraping, and YAML configuration, his work improved the completeness and reliability of governance analytics, providing a deeper, more accurate historical record of parliamentary membership.
