DevOps Engineer
I’m Daniel, a DevOps engineer who enjoys keeping complex infrastructure reliable, secure, and efficient. I focus on continuous improvement, automation, and fostering calm, collaborative environments.
Experience
Inovex GmbH — Cloud Engineer
- Designed and implemented Azure landing zones, tailoring them with best practices and client-specific requirements while keeping tight contact with the client.
- Introduced reusable Terraform, Terragrunt, and Kapitan modules that modernized an enterprise legacy estate and dramatically increased standardization.
- Migrated ageing Kustomize deployments to maintainable Helm charts, cutting deployment time for microservices by roughly 20%.
- Integrated microservices into a centralized deployment architecture to improve reusability and maintainability.
- Refactored GitLab CI/CD pipelines, trimming build and release times by around 30% across half of the client product portfolio.
- Delivered parameterized, dynamic pipelines that made delivery logic clearer and more resilient.
Knuddels GmbH — Linux Sysadmin
- Operated a hybrid estate with a 12-node Kubernetes cluster and 70+ Linux servers across cloud and on-premises environments.
- Halved downtime by redesigning the flagship product’s release process, pairing it with automation built in Ansible.
- Raised overall availability through proactive maintenance, upgrades, and observability tuning (Thanos, Prometheus, ELK) that reduced storage needs by ~40%.
- Automated port-security checks with Ansible Jinja2, Prometheus Blackbox, and Bash to eliminate manual testing.
- Implemented Wazuh and Trivy to cut critical vulnerabilities by 30% within two weeks while rolling out cost-efficient metrics/log storage.
- Delivered repeatable release tooling that dropped environment rollout times from two hours to ten minutes and partnered closely with development to keep releases predictable.
