Senior🎓
Top SchoolTodd Lyons is a seasoned DevOps and SRE engineer with 14 years of experience designing, scaling, and maintaining high-availability Linux systems using Kubernetes, Terraform, Jenkins, and Git-driven workflows. Based in California, he has delivered production-grade AWS infrastructure and CI/CD improvements across roles at SpotOn, Cognosante, and PGi, and runs his own consulting practice focused on traffic and load scaling. An active open-source maintainer and contributor, Todd has committed to widely used projects including Exim (improving SMTP handling and logging) and kops (adding interactive rolling-update features). He blends deep systems-level expertise—rooted in early work administering email, DNS, and NetApp systems—with modern cloud-native tooling, making him equally comfortable troubleshooting kernel-level issues or iterating on operator UX. Colleagues rely on him for pragmatic automation that balances operational safety with velocity.
