Cristiana Man worked on the zendesk/copenhagen_theme repository, focusing on front end development using React, JavaScript, and styled-components. She upgraded the Zendesk Garden UI library to version 9.12.0, which enhanced component consistency and reduced future upgrade risks by ensuring compatibility with the latest features. To improve test reliability, Cristiana introduced a custom render function that wraps tests with a theme provider, enabling consistent theming across the testing suite. While no major bugs were fixed during this period, her work delivered stability improvements through dependency upgrades and more robust testing infrastructure, reflecting a thoughtful approach to maintainability and user interface quality.
