Worked on the gitbutlerapp/gitbutler repository to enhance the user interface by expanding file icon support for TypeScript and GraphQL extensions. Focused on updating the UI component library, the developer introduced new icon mappings for .cts, .mts, and .graphqls file types, improving file-type visibility and streamlining navigation throughout the codebase. The implementation leveraged TypeScript and front end development skills, ensuring changes were well-documented and integrated with existing icon rendering flows. This work established a scalable approach for future extension support, reducing the effort required for similar updates and contributing to more efficient file discovery for developers across the project.
