Top SchoolJohn Mercer is a DevOps Security Engineer with 13 years of experience blending software engineering and information security to solve complex operational problems. He has led CI/CD and cloud migrations across PCF, GCP, EKS, and OpenShift, built high-availability tooling like Artifactory on Kubernetes, and integrated security and quality gates such as SonarQube into pipelines. Comfortable in both front-end and backend contexts, he has modernized legacy stacks (AngularJS to Angular, LAMP to containerized deployments) while coaching teams on Git, Docker, and CLI best practices. A pragmatic thinker who moves between hands-on coding, infra automation, and sysadmin duties, he now focuses on securing DevOps workflows at Hagerty from his base in Marietta, GA. Outside of work he’s an avid dog lover and early adopter mindset hinted by projects like mining Bitcoin on hobbyist hardware during his studies.
