PROFILE
Erwin Van Der Valk
Erwin van der Valk contributed to the DuendeSoftware/foss repository by delivering targeted improvements in release automation, workflow reliability, and codebase maintainability over a three-month period. He automated release processes by deriving version information directly from the target branch, reducing manual input and streamlining CI/CD pipelines using C# and YAML. Erwin also enhanced performance testing realism by tuning Chaos Monkey’s unauthorized response rates, which decreased test flakiness and better simulated production scenarios. Additionally, he improved code hygiene by cleaning up logger configurations, making the codebase easier to maintain. His work demonstrated solid backend development and CI/CD configuration skills throughout.
