Senior🎓
Top SchoolRory Sexton is a Cloud Software Engineer with 11 years of experience building high-performance networking and virtualization software, most recently focused on performance and power efficiencies for cable broadband on Intel CPUs. He has deep systems expertise across networking, DPDK, container orchestration (Kubernetes, Docker, containerd, OpenShift), Linux, C and Python, and contributed notable platform-aware telemetry enhancements to the widely used collectd project. Rory spent nearly a decade at Intel’s Network Platforms Group driving optimizations and Open vSwitch work before moving to Siemens EDA to apply cloud-native practices to EDA tooling. He combines low-level CPU and power-management knowledge with cloud and orchestration skills, enabling practical cross-layer performance gains that are often overlooked. Based in Ireland, he brings an engineer’s attention to instrumentation and measurable improvement across both firmware-adjacent and cloud stacks.
