Infrastructure, reliability and security
Open-source maintainer, security analyst and technical writer.
What I do
I maintain Caddy and rsync, investigate security problems and build tools for work that needs to be repeatable and checked. I also write about infrastructure and contribute to public policy where implementation details matter.
Who I am
I am Zen Dodd, usually Tao online. I am an Australian infrastructure and security practitioner, open-source maintainer and technical writer. Most of my work sits close to production: web servers, Unix tooling, cloud systems and the security decisions around them.
