Fajar Hide developed a user experience feature for the decolua/9router repository, enabling users to deselect models directly within ComboFormModal and ComboDetailPage. This enhancement allows model removal without closing the modal, streamlining the configuration process and reducing user interaction steps. Fajar approached the task with a focus on modularity and testability, ensuring that the changes were clean and had minimal impact on existing code. Working primarily with React and JavaScript, Fajar’s front end development contributed to more efficient model management workflows. The work addressed a specific backlog item and laid the foundation for future improvements in model configuration.
