• Operated a highly available RHEL and WildFly/JBoss environment for public geospatial services
• Standardised server configuration and application deployments with Ansible
• Ensured reliable production operations, structured handovers and technical documentation

Production SRE and DevOps work in a containerised environment, including Kubernetes-based workloads, GitLab CI/CD, Docker and a central ELK logging pipeline for proactive error analysis.

Enterprise monitoring and logging in a migration context: automated existing monitoring setups, migrated from Icinga to Icinga2 and extended the ELK and Graphite/Grafana stack — embedded in live production operations and troubleshooting.
