About

Hi — I'm a network engineer. I spend my days keeping packets flowing and my nights breaking (then fixing) things in the lab. This site is my public notebook: designs, configs, troubleshooting write-ups and automation experiments.

Experience

I work across the full network stack — from campus access and wireless, through the WAN and SD-WAN edge, into the data-center fabric. Lately I've been focused onnetwork automation and telemetry: replacing manual CLI work with Python and Ansible, and swapping SNMP polling for streaming gNMI where I can.
