During May 2025, Kozlov focused on front-end development for the SophieM09/the-grand-code-hotel-10 repository, delivering a new Testimonials Section to enhance the site’s social proof. Using HTML and CSS, Kozlov implemented the section’s layout, styling, author information, and sample author images, ensuring a visually consistent and user-friendly interface. After the initial build, Kozlov addressed reliability by refining CSS references and image paths, which improved rendering across different environments. The work was delivered through incremental commits, reflecting a methodical approach to feature delivery. This contribution laid a solid foundation for future content management and improved the maintainability of the site’s UI.
