Focusing on frontend theming and user interface design, Christophe established consistent branding across the integration, aligning visual elements with product guidelines to improve user experience. The work involved close collaboration and use of Git-based workflows to ensure traceability and future maintainability, linking changes to relevant issues and pull requests.
