During November 2025, Stefan Roeck focused on enhancing the accuracy of user-facing documentation for Gatling metrics in the gatling/gatling.io-doc repository. He identified and corrected a configuration parameter typo that could have led to misconfiguration in Gatling reports, ensuring the documentation aligned with the current codebase. Stefan’s technical writing and documentation skills, particularly in Markdown, were applied to deliver a clear and precise update. By co-authoring the change, he improved the maintainability of the documentation and reduced potential onboarding and support issues related to metrics configuration. The work addressed a targeted bug fix rather than introducing new features.
