During January 2025, Ek Speeder contributed to the uBlockOrigin/uAssets repository by delivering targeted improvements in ad blocking and user interface layout. They addressed unwanted ads on Trakt.tv by implementing filter list rules that block elements with specific IDs linked to advertising, enhancing the browsing experience. Additionally, Ek improved the PlantUML editor’s layout by introducing custom CSS-based filters to refine the sidebar and bottom section, reducing visual clutter. Their work demonstrated proficiency in filter list management, web filtering, and CSS-driven DOM manipulation. Each change was carefully tracked with clear commit messages and issue references, reflecting disciplined and maintainable engineering practices.
