Kernel ↔ userspace integration · low-latency, fault-tolerant architectures
6+ years building production-grade systems in C, C++ and Go across the defense and telecom domains — from 24/7 high-availability IP-PBX platforms to tactical routing systems with kernel-level packet processing and encrypted tunnel management.
I work close to the metal: eBPF/XDP datapaths, Netfilter, IPsec/XFRM, dynamic mesh routing, and transparent proxy / deep-packet-inspection pipelines.
- Kernel-level packet processing — eBPF / XDP, Netfilter, Linux kernel ↔ userspace integration
- Secure tunneling — IPsec / XFRM tunnel management & session lifecycle control
- Tactical & mesh routing — OSPF, OLSR, traffic management for dynamic networks
- Transparent proxy & DPI — lwIP, Suricata, inline IPS/IDS
- Real-time communication — SIP/SDP, RTP/RTCP, call-control state machines
