Rockstar🎓
Top SchoolJonathan Mainguy is a DevSecOps/Platform engineer with 12 years of experience building and operating cloud-native infrastructure for companies like Red Hat, Bandwidth, CVS Health and McDonald’s. He blends hands-on systems reliability work—Kubernetes, Golang operators, Ansible contributions to core Ansible repos—with team leadership, CI/CD architecture (GitHub Actions, ArgoCD) and developer experience improvements. An active open-source contributor, he authored the Coastie Kubernetes operator and has improved key Ansible modules used widely in automation workflows. His background in accounting gives him a pragmatic, metrics-minded approach to risk and process, and he’s known for turning proofs-of-concept into production-grade tooling. Outside work he builds things by hand—guitars, smokers and wood projects—which mirrors his preference for practical, maintainable engineering.
