About

Hello
#

I help keep the internet running and I insist it stays fast, reliable, and privacy-preserving. Most days that means working on critical infrastructure like large-scale networks, DNS, and routing protocols while leading the teams that build and operate them. I grew up with UNIX, never really let go of it, and have spent time across various unices over the years. These days I mostly work with FreeBSD and Linux when debugging odd behavior in production.

What I Do Now
#

  • Internet infrastructure architect with 20+ years designing and operating global networks and services
  • Network engineer focused on BGP, DNS, eBPF, and keeping things reliable at scale
  • UNIX systems engineer with deep FreeBSD expertise and plenty of battle scars from working across different UNIX-like systems
  • Security researcher tracking how networks fail, sometimes on purpose
  • Instructor delivering advanced UNIX and TCP/IP courses to ops teams who prefer live demos over slides
  • Software engineer building tools in C, Go, Python, Perl, and Lua; the code I publish lives on GitHub

Projects You Might Know
#

  • Contributor and developer in the FreeBSD Project since the 2000s; my commit history and code reviews document the trail
  • Lead behind the DNSDiag toolkit used by operators to measure DNS performance and catch hijacks before customers do
  • Rearchitected legacy systems and led engineering teams across multiple time zones to modernize infrastructure
  • Long-form research at RIPE Labs covering DNS hijacking, public resolver behavior, and regional reachability
