During June 2025, Kadu worked on the caelum/gnarus-api-assets repository, delivering new course data and color mappings for the Expandalura platform. He expanded the repository’s structure by creating directories and files to support scalable content delivery, and updated environment checks to ensure seamless integration of Expandalura. Using JavaScript and shell scripting, Kadu stabilized the build process by correcting asset filename references, which improved build reliability and reduced potential errors during continuous integration. His work combined frontend development, build automation, and DevOps practices, resulting in a more robust platform foundation and enabling future content expansion with greater confidence and maintainability.
