Worked on the ckeditor/ckeditor5 repository to deliver enhanced media embed functionality and user experience improvements. Developed a robust media embed resize feature with drag handles and aspect-ratio awareness, enabling responsive resizing across multiple providers, including Spotify. Addressed cross-platform input handling by fixing native undo and redo behavior in source editing mode, ensuring consistency for keyboard shortcuts on Windows and macOS. Refactored the media widget resizer logic for better performance and maintainability, simplifying the codebase by removing unnecessary flags. Utilized JavaScript, TypeScript, and CSS to implement features, write tests, update documentation, and maintain backward compatibility throughout the development process.

Apr 1, 2026April 2026: CKEditor 5 delivered targeted UX and media controls enhancements, strengthening content reliability and editor productivity. Key changes include fixing native undo/redo in source editing mode to align with browser behavior across platforms (Ctrl/Cmd, caps lock, macOS Cmd+Y) and delivering a robust Media Embed Resize Feature with drag handles, aspect-ratio awareness, and multi-root resizing, supported by tests and documentation. These efforts reduce editing friction, improve output quality across providers, and lay the foundation for scalable media controls. Demonstrated strengths in plugin architecture, cross-platform input handling, test coverage, documentation, and backwards-compatible refactors.
