Core expertise
A consistent career thread: Linux → enterprise operations → automation → monitoring & logging → observability → security observability.
Enterprise Linux & Infrastructure
Design, operation and troubleshooting of business-critical Linux platforms, with a focus on RHEL, high availability, middleware, lifecycle management and reliable production operations.
- RHEL as well as Debian/Ubuntu experience
- Highly available Linux platforms

- Puppet as earlier practical experience
- Deployment standardisation
- Repeatable provisioning and configuration
- CI/CD and GitLab pipelines as a supporting skill
- Change-, release- and rollout-oriented operations
