Summary
🤩
Rockstar🎓
Top SchoolEdward Haas is a Principal Software Engineer with 11 years' experience specializing in networking for virtualization, currently making networking flourish in OpenShift Virtualization at Red Hat. He brings deep expertise across data and control planes (SDN/NFV), network acceleration, and VM networking in projects like oVirt and KubeVirt, with hands-on C/C++ and Python development and DevOps automation. A long-time open-source maintainer, he has improved backend robustness and networking components in widely used virtualization projects and refactored critical code paths to prevent issues like IP duplication. Edward champions engineering best practices—TDD, CI, design patterns—and consistently seeks new DevOps solutions to boost quality and cycle time. Based in Israel, he combines low-level packet-processing experience (DPDK, multicore optimization) with higher-layer protocol work (HTTP, SIP/VoIP), a blend that makes him effective across the stack.
