Graham Woods developed Ruby 3.4 compatibility for the elastic/apm-agent-ruby repository, focusing on agent development and CI/CD configuration. He updated configurations and dependencies to support the new Ruby version, addressing challenges such as Sidekiq job name detection and MongoDB spec handling. His work included refining test stability across multiple Rails version combinations, reducing flakiness in continuous integration and improving deployment readiness. Using Ruby and YAML, Graham ensured the agent remained reliable across environments. Although the scope was limited to one feature over a month, the work demonstrated careful attention to cross-version support and robust testing practices within the Ruby ecosystem.
