Summary
👤
Senior🎓
Top SchoolStefan Reimer is a founder and seasoned cloud and network security engineer with 14+ years of hands-on experience designing and operating resilient, large-scale infrastructure. He blends deep expertise in cloud platforms (AWS, OpenStack, Kubernetes, Docker) with low-level network mastery (L2/L3, SDN, VxLAN) and practical security skills including penetration testing and web app assessments. Stefan has led cloud architecture and senior engineering roles at companies like TriNimbus and Demonware and now runs Zero Down Time, focusing on automation, orchestration, and reliable deployments. Comfortable across the full stack—from JVM tuning, databases and NoSQL platforms to monitoring stacks (ELK, Nagios, Zabbix)—he’s as likely to troubleshoot a production packet flow as to script an automated rollout. Based in Vancouver, he pairs academic engineering training with a pragmatic approach summed up in his favorite line: “In theory, theory and practice are the same. In practice, they're not.”
