Worked on the cloudfoundry/diego-release repository to deliver an upgrade of the Envoy proxy from version 1.36.2 to 1.37.0, focusing on enhancing both performance and security within the platform. Leveraged skills in containerization, DevOps, and system administration to implement and validate the upgrade, utilizing Shell and YAML for configuration and automation. The process included integrating the change through CI/CD pipelines, which ensured stability and improved monitoring around the proxy layer. This approach reduced routing risks and increased operational visibility, reflecting a methodical and collaborative engineering effort centered on infrastructure reliability and maintainability over the course of the month.
