Paal Eye focused on maintenance and build system improvements for the ghostty-org/ghostty repository, addressing technical debt and enhancing long-term maintainability. Over two months, Paal removed the unused utf8proc dependency, simplifying the codebase and reducing bundle size, which streamlined future upgrades and improved CI efficiency. He also extended the CMake-based cleanup process to include Zig build outputs, preventing leftover artifacts and ensuring reproducible, reliable builds. Working primarily with CMake and Zig, Paal demonstrated a methodical approach to dependency and build hygiene, contributing to a cleaner development environment and lowering maintenance overhead, though his work did not involve new feature development.
