This is [char.blog](https://char.blog), a collection of technical notes, implementation writeups, and references. Some are polished. Most are in progress. I work as a Technical Consultant and Senior Engineer at a Managed Service Provider, mostly across cloud infrastructure, networking, cybersecurity, automation, and production support. Outside of work, I’m currently learning to boulder and spend most of my time researching, programming, listening to music (mostly jazz and classical) or doing some type of endurance sport, usually cycling or running. If you have a question related to a network I manage or control, please send an email to the address listed on the respective WHOIS contact. If it is a P1 issue or security vulnerability, please include “P1” or “Security” in the subject line.
