Top SchoolDenis Meltsaykin is a Senior DevOps Engineer based in Prague with 11 years of experience hardening and maintaining enterprise OpenStack distributions. He leads maintenance and stabilization efforts at Mirantis, delivering 99% of updates on time while writing patches across multiple languages, maintaining CI/CD pipelines, and mentoring colleagues. A former datacenter and ISP network architect, he brings deep Linux/FreeBSD tuning skills and hands-on carrier-grade experience with Juniper and Cisco, having rebuilt cores and implemented BRAS and Q-in-Q without downtime.
