Worked on cross-platform packaging and build system improvements for the ocaml/opam-repository, focusing on enhancing Windows support and maintaining parity with Unix-like environments. Delivered updates to PCRE and libcurl packaging, standardizing build tooling with pkg-config and refining metadata for licensing and authorship consistency. Used OCaml, Shell, and Ruby to implement these changes, ensuring reliable package management and smoother onboarding for Windows developers. Later contributed to chenrui333/homebrew-core by stabilizing the Semgrep auto-update workflow, addressing a bug that prevented unstable updates from reaching users. This work emphasized configuration management, package reliability, and careful handling of automated update processes.
