Summary
👤
Senior🎓
Top SchoolRadek Zajic is a Senior Product Architect and IPv6 advocate with nine years of focused experience designing, deploying and operating large-scale Windows/Linux server environments and CDN infrastructure. He has led content delivery and multi-CDN engineering for major streaming platforms and currently shapes product architecture at Akamai while also running his own consultancy, sixploy. Radek combines hands-on network engineering (IPv6 migrations, routing, 100GbE) with automation and IaC expertise—Kubernetes (with Cilium), Terraform, Puppet and GitOps—plus scripting in Python, Bash and Go. He’s equally fluent in observability and log processing stacks (Prometheus/Grafana, Vector, ELK) and in carrier-grade networking gear (Cisco, Juniper, Arista, F5). A pragmatic technologist who “eats his own dog food,” he frequently speaks at conferences and publishes talks online, turning operational experience into practical, repeatable improvements. Based in Prague, he pairs formal engineering education with a track record of reducing tech debt and pushing IPv6-only deployments from concept to production.
