Ryan Thornton developed automated TLS certificate management for CEOS nodes in the srl-labs/containerlab repository, focusing on enhancing security and streamlining user workflows. He implemented a system in Go that generates and loads TLS certificates automatically, removing the need for manual configuration in topology files. This approach improved the onboarding experience and reduced operational overhead by eliminating repetitive certificate management tasks. Ryan’s work included backend development, containerization, and networking, with thorough documentation and internal testing to validate the new automation. The feature was delivered as a clean, collaborative code change, demonstrating depth in secure infrastructure automation within a short timeframe.
