Riley Jones developed a responsive chess board rendering and viewer mode UI for the Kaggle/kaggle-environments repository during July 2025. Focusing on front end development, Riley implemented dynamic sizing for chess board squares and pieces, allowing the interface to adapt seamlessly to various container sizes. Using JavaScript and CSS styling, Riley also introduced conditional rendering of the title and status in viewer mode, enhancing clarity and usability for users evaluating chess environments. The work addressed the need for adaptable UI components across devices, demonstrating a solid grasp of DOM manipulation and responsive design principles within a focused, single-feature engineering effort.
