Senior🎓
Top SchoolDavid Höppner is a DevOps engineer with 16 years of experience building and operating cloud-native and infrastructure systems across academia and industry in Germany. He has deep hands-on expertise in Kubernetes, OpenShift, OpenStack, Prometheus, and automation with Go, Python, Rust and Ansible, and has maintained critical services like GitLab, Jira, Elasticsearch and high-availability stacks. His contributions to illumos and OpenIndiana show comfort with low-level networking and cross-architecture build systems, reflecting rare kernel-to-cloud breadth. At Heidelberg University he combined platform engineering with data workflows (Scrapy, Spark) and custom deployment tooling, and later advised on big-data and cloud-native solutions as a consultant. Now at DKB Service he continues to apply pragmatic reliability and observability practices to production infrastructure while bringing a multilingual, research-informed perspective from an MA in Asian studies.
