Hi, I'm Juancho 👋

I've been writing software for more than 25 years and I still get a kick out of it. These days most of my tinkering happens at home: making the house smarter with Home Assistant and self-hosting the services I use every day. This is where I share what I learn along the way, including the things that didn't work the first time.
