In March 2026, Fiona O’Carr worked on the Submitty/Submitty repository, delivering a targeted UI/UX update to improve branding accuracy for St. Patrick’s Day. She replaced the previous four-leaf clover imagery with a shamrock, ensuring the holiday symbol was correctly represented in the interface. The update was implemented as an asset-only change using CSS, HTML, and JavaScript, requiring no backend modifications and presenting minimal risk to the system. Fiona verified the update through manual visual inspection, documenting the process clearly. The work demonstrated focused front end development and UI/UX design skills, addressing a specific branding issue with precision.
