PROFILE
Paul Marquess
Worked on the Perl/perl5 repository, delivering multiple upgrades and maintenance releases for core compression modules such as IO-Compress, Compress-Raw-Zlib, and Compress-Raw-Bzip2. Focused on improving stability, security, and cross-platform compatibility, the work included implementing zlib-ng 2.x support, refining CI/CD workflows, and modernizing dependency management. Enhanced module versioning, packaging, and release engineering practices while introducing security documentation and automating version checks. Used Perl for backend development, module maintenance, and testing, ensuring reliable archive handling and streamlined releases. Addressed compatibility issues, improved automation, and maintained robust package management, contributing to a more maintainable and secure compression stack.
