Worked on Lundalogik/lime-elements, focusing on stability and user experience improvements for core front end components. Addressed File Viewer reliability by deferring PDF blob URL revocation, ensuring documents remain accessible during dynamic portal DOM moves. Enhanced the Chip Set component to keep input fields visible when users have uncommitted text, reducing navigation friction. Improved the Picker component’s keyboard navigation by guarding against missing list items and supporting sectioned results with separators, including a new demo. All changes were implemented using React and TypeScript, demonstrating careful attention to DOM lifecycle management and robust component design for dynamic user interfaces.
