Hey, I'm Joe. I help developers build cool stuff - through demos, blog posts, talks, videos, whatever works.

Leading developer marketing at CData. Outside of work I run a40+ container homelab, watch way too many movies, and build things that probably shouldn't be connected to the internet.

I once built an IoT cat toilet and gave a conference talk about it. Also aTEDx speaker. I contain multitudes.
