Worked on the team-mirai/policy repository to modernize continuous integration workflows by upgrading Markdown link checking in CI. Migrated from a legacy configuration to umbrelladocs/action-linkspector, introducing a dedicated YAML configuration file to define directories, ignore patterns, and specialized handling for government and social media links. This transition eliminated obsolete configuration files and streamlined the process for maintaining documentation link integrity. Leveraged skills in CI/CD, configuration management, and GitHub Actions, focusing on YAML for configuration. The improvements reduced false positives in link checks, enhanced the reliability of documentation, and accelerated pull request feedback cycles without introducing new bugs during the period.
