Backbone, 2025
A 40-site backbone redesign across two countries. BGP, EVPN, and a lot of quiet maintenance windows.
Lead architectNetworks that stay quiet under load.
Selected work
Architecture, migration and the unglamorous work that keeps a network up. Three projects, three different kinds of silence.
Networks should
disappear.
I design networks that nobody has to think about: routing, cloud, automation, and the process that keeps a change from becoming an incident.

Let’s make it
quiet.
