Sakura Inoue focused on build system reliability and developer experience across several Input Output HK repositories. On catalyst-ci, Sakura updated documentation dependencies and lockfiles using Python tooling, improving CI stability and reducing onboarding friction for contributors. In the catalyst-voices repository, Sakura enhanced onboarding by configuring VS Code to recommend the Justfiles extension, streamlining syntax support for new developers. For catalyst-libs, Sakura upgraded Rust dependencies and introduced a CUE-based metadata blueprint, ensuring reproducible builds and preparing the project for release tagging. Throughout, Sakura demonstrated depth in dependency management, build system configuration, and cross-language tooling, delivering maintainable improvements without introducing user-facing bugs.
