I’m Matt Horn. I’ve worked in software and security engineering for about fifteen years. Most of that time went to identity, access management, and cloud infrastructure at companies you’ve probably heard of; the resume has the list. More recently I’ve been focused on AI/ML infrastructure and the security problems that come with it.

I write here occasionally: essays on security and AI, and once in a while some very short fiction.
