Software Developer & Home Automation Enthusiast
I’m Amthonie, a PHP developer living in Naarden. I work in travel technology, and in my spare time I enjoy experimenting with thoughtful home automation and spending time in nature. In both life and tech, I try to keep things local, private and sustainable, picking up new skills as I go. Over time I’ve learned to build things that provide real value1, having lost enough hours on features that looked appealing but helped no one. More about me
1. I know this page breaks my own rule; the ongoing tinkering is simply too enjoyable.

Satire · Fiction
The Interplanetary Chronicle
Because reality isn’t ridiculous enough: a satirical outlet reporting boldly, inaccurately and with great enthusiasm on the state of the cosmos. Proudly the worst tabloid in this galaxy and beyond.

Worth a Click
A small collection of people, causes and places that matter to me.
