Worked on the GetStream/stream-video-js repository to enhance UI stability and streamline moderation workflows. Addressed a UI issue where the blocked participants header was hidden due to a restrictive CSS display property, which prevented moderators from efficiently managing blocked users. By updating the CSS from 'none' to 'flex', restored both visibility and interactive functionality to the header, aligning the interface with product requirements. This targeted fix improved moderator efficiency and reduced friction for end users managing participant lists. The work demonstrated attention to detail in front end development, with a focus on CSS and user interface consistency throughout the moderation experience.
