Summary
🤩
Rockstar🎓
Top SchoolMazdak Nasab is a Senior Software Engineer in Vancouver with 11 years of experience building high-performance, secure network systems for cloud and data center environments. He specializes in systems and network development in C, Go, and Rust, and automates infrastructure with Python and Ansible. Deep expertise in the Linux networking stack—eBPF/XDP, Netfilter/iptables, TC, Socket API and IPVS—drives his work on resilient, high-availability architectures. At Tigera and as a core contributor to Project Calico, he enhanced BPF dataplane performance, added IPv6 support, and integrated XDP with policy engines to improve packet processing and observability. Previously he applied SRE and network expertise at Ericsson and Enea, bridging research, production reliability, and protocol-level implementation. Known for pragmatic code refactors and production-focused instrumentation, he combines low-level packet plumbing with cloud-native networking design.
