I automate deployments, improve reliability, and make systems easier to support and scale.At KNIME I managed AWS and Kubernetes with Terraform, Helm, and ArgoCD. Uptime reached 99.95 percent while release cycles improved and manual toil dropped. I improved CI and CD, built dashboards and alerting in Grafana and Prometheus, and cut incident response times by 30 percent.Earlier I ran Pulse Design where I delivered full stack apps and production environments for clients across the U.S. That mix of development and operations helps me bridge teams and ship resilient systems.Core focus: SRE, DevOps, Cloud Engineering, Infrastructure as Code, Observability, GitOps, CI and CD, Automation, Incident Response, Cost Optimization.Open to senior SRE and DevOps roles.
