Amanda Fernandez focused on stabilizing the CI pipeline for the puppetlabs/puppetlabs-puppet_agent repository by addressing DNS resolution issues affecting Task Acceptance Tests in Azure environments. She implemented a targeted fix using YAML and GitHub Actions, configuring network interfaces to use Twingate DNS servers and flushing DNS caches to prevent Azure DNS from interfering with Twingate connectivity. This solution improved Artifactory reliability and reduced test flakiness, accelerating feedback cycles and enhancing deployment traceability. Amanda’s work demonstrated a thorough understanding of CI/CD workflows and networking, delivering a robust bug fix that directly addressed a critical infrastructure challenge within the repository.
