Rockstar🎓
Top SchoolTomas Hlavacek is a seasoned network and systems engineer with 13 years of hands-on experience designing, automating and operating large-scale Internet infrastructure, currently based in the Zürich area and working as a Senior Network Engineer at DFINITY while running his own consultancy. He combines deep theoretical computer science training with practical low-level development—having contributed to projects like the Linux kernel, U-Boot, BIRD and Knot DNS—and brings PhD-level cybersecurity research experience to operational challenges. Tomas excels at automation (Ansible, Python), complex network design (Cisco, Juniper, SoNIC) and troubleshooting, and recently led automation and upgrades of a leading European IXP fabric. Equally comfortable in embedded/RT systems and high-availability server platforms, he blends kernel- and firmware-level development with DevOps practices to deliver resilient, scalable networks. A pragmatic problem-solver, he often bridges gaps between research, development and operations to turn cutting-edge protocols into reliable production services.
