Summary

Rockstar🎓
Top SchoolDmitriy V is a seasoned consultant and systems engineer with 17 years delivering scalable big-data and cloud-native infrastructure across finance, healthcare and SaaS. He blends deep hands-on expertise in Hadoop/Spark, Kubernetes/OpenShift, and CI/CD with strong security and automation chops (RHCArch, Spark Certified Developer, Scrum Master), having built multi-tenant recoverable analytics platforms and GDPR-ready data pipelines. An active open-source maintainer and contributor—most notably to the popular vagrant-libvirt provider and kops networking/etcd improvements—he bridges DevOps, backend and data engineering. Comfortable from kernel-level virtualization to data visualization, he pairs scripting and systems programming skills (Ruby, Python, Scala, Go) with production experience in Chef/Puppet/Ansible, FreeIPA/LDAP integration and SIEM/IDS design. Not obvious from titles: he also mentors engineers and has a track record of creating bespoke automation (PXE/Foreman, encrypted k8s installs, network device Ansible modules) that removes manual toil. Based in Heidelberg, Germany, he prefers Chef but is pragmatic across the full stack.
