Gabriela Bar developed and maintained core functionality for the wix-incubator/pro-gallery repository, focusing on front-end stability and user experience. Over two months, she addressed three critical bugs using JavaScript, improving gallery initialization and video playback reliability. Her work ensured that onGalleryScroll events fired correctly during initialization, even without an active item, by introducing a fallback to the window scroll position. She also resolved issues with video playback when the active index was undefined and enhanced blueprint caching by detecting scrollBase changes. These targeted fixes improved initial render consistency, analytics accuracy, and UI reliability, demonstrating depth in front-end development and debugging.
