Most of what I build, you’ll never see.
I’m Onnwen L.G. Cassitto L’Hostis, a software engineer in Milan. I spend most of my days on the parts that never make it into a screenshot.
One generation down
L. is for Leonida.
My grandfather. I never met him, but he’s been sitting in the middle of my name for as long as I’ve had one.
Two thousand years down
G. is for Garamante.
The Garamantes farmed the Libyan Sahara. To water their fields, they dug tunnels by hand, all the way down to the groundwater. From above, all you could see was a line of holes in the sand.
Five thousand years down
The water was older than all of them.
The rains had stopped some five thousand years earlier. Every field they watered drank rain that fell before anyone could remember. I think about that a lot.
This is where I work.
Architecture, performance, the small decisions that keep an app standing. When I get them right, you won’t notice any of them.

Everything it takes for an app to feel like nothing at all. If you have to think about it, I’m not done.

I designed it and built it, start to finish. Getting it to work was the easy part. Getting it to feel right took longer.
