Subject / Headline: Senior Kernel & Quantitative Infrastructure Engineer | eBPF & High-Frequency Network Adversary About Me: I am a senior, low-level infrastructure engineer specializing in Adversarial Networking (L3–L7) and High-Frequency Execution Infrastructure. Over the past several years, I have engineered proprietary, production-grade systems operating in highly hostile, low-latency, and zero-trust environments. Because my work directly drives high-net-worth quantitative trading and military-grade privacy overlays, all my core codebases are entirely closed-source (Private/NDA-restricted), with zero public GitHub footprints. I do not build vanilla web apps; I orchestrate traffic inside the Linux kernel. My core competence lies at the intersection of Linux Kernel Observability/Networking (eBPF/XDP) and Ultra-Low-Latency Order Execution. In the networking domain, I design and implement L3-L7 stealth transit layers. I have custom-engineered a stateful egress IP hot-swapping infrastru
