Said Rehouni expanded Mac Catalyst support for the expressvpn/wolfssl-rs repository by updating build scripts to target both ARM64 and x86_64 Mac Catalyst architectures. He implemented these changes using Rust and Shell, ensuring the build system could reliably produce Mac Catalyst binaries. Said also enhanced the CI/CD pipeline with GitHub Actions and YAML, introducing automated testing for the new targets. This work improved cross-platform development workflows and enabled faster, safer shipping of Mac-focused builds. Over the month, his contributions focused on build tooling and CI configuration, deepening platform coverage without introducing or addressing any major bugs during this period.
