Kara Atsar worked on the MuViCo/MuViCo repository, focusing on improving the onboarding experience for new users. She implemented a targeted change to the front page by reordering onboarding videos, ensuring that “Show Mode in Action” appears before “Creating and Editing a Presentation.” This adjustment aimed to accelerate user understanding of MuViCo’s core features and reduce cognitive load during onboarding. Using React and JavaScript, Kara delivered the feature with clear commit traceability and minimal risk, as the changes were isolated to content ordering. No bugs were reported during this period, reflecting a focused and low-complexity engineering contribution in front end development.
