About

I'm Casey MacPhee - a Staff Engineer at Liberate, where I build production AI agent frameworks for high-stakes workflows and customer interactions: agents that have to do the right thing, prove it, and keep doing it at scale.

Before Liberate, I spent years in backend and platform engineering - the kind of work where you learn the level of rigor and system design necessary to support enterprise customers at scale. That mindset is what drew me to agent systems: they're the most interesting distributed systems problem in software right now, and most of the field is still pretending the hard parts don't exist.

I'm writing here about the parts that actually matter to me, not opinions about where AI is headed - your guess is as good as mine.

I got my start in tech in Seattle and now live in Boise with my family. When I'm not problem-solving, I'm usually on a trail somewhere in the Idaho foothills or up in the mountains.

Opinions are my own and don't reflect the views of any current/former employer.
