Kostya Lasiy developed a drag-and-drop reordering feature for experience and education sections in the srbhr/Resume-Matcher repository, focusing on enhancing the resume builder’s user experience. He designed a generic DraggableListItem component in React, integrating it with the @dnd-kit library to support both mouse and keyboard interactions, ensuring accessibility compliance. The implementation emphasized UI/UX design principles and maintained consistent styling across drag handles. By establishing an extensible pattern, Kostya enabled future expansion to other resume sections such as projects or custom entries. His work demonstrated depth in front end development using JavaScript and TypeScript, with attention to accessibility and maintainability.
