Worked on the ZeitOnline/vivi repository to deliver two backend features focused on enhancing podcast metadata integration with external platforms. Extended the IPodcast interface and its implementation to support additional Spotify RSS feed attributes, including explicit, author, category, and podcast_type, thereby improving data quality and compatibility. Added an rss_image attribute to the Podcast interface, updating constructors and equality logic to ensure seamless handling in PodcastSource. All changes were documented in the project changelog for traceability. The work was implemented using Python and centered on API design and backend development, with an emphasis on forward compatibility and clear business value.
