John Mark

I am a Senior DevOps Engineer with over six years of DevOps experience and three years as a Linux administrator, focused on designing and automating cloud infrastructure and delivery pipelines across AWS and Azure. I have led migrations, implemented Infrastructure as Code with Terraform and ARM, and built CI/CD pipelines using Jenkins, GitLab CI, GitHub Actions and Azure DevOps.

I specialize in containerization and orchestration using Docker, Kubernetes (EKS/AKS), OpenShift, and related tooling such as Helm and Istio to enable reliable rollouts and minimize downtime. I also build monitoring and observability solutions with Prometheus, Grafana, Splunk, and Azure Monitor, and automate operations with Ansible, Puppet, Chef, and scripting in Python, Bash and PowerShell.

I deliver operational excellence for highly regulated and high-value systems — including supporting SWIFT payment platforms — by producing runbooks, automation, cost-optimization recommendations, and strong incident response practices. I hold certifications in Azure Administration, Kubernetes, AWS, and Terraform, and I seek to drive resilient, auditable, and efficient platform engineering outcomes.
