Welcome to my corner of the internet!

I'm Arthur. Brazilian from Belém, now in Berlin, where I build things that sit between the digital and the physical. At HOLOPLOT during the day, and in various corners of my apartment the rest of the time.

Most of what catches my attention lately is AI: I run a small fleet of agents that handle my household, my calendar, and the admin I was never going to do anyway. Before that, it was photography, cycling, homelab, playing guitar, and many others. The through-line is probably curiosity about tools, and stubbornness about using them on my own terms.

Why a website?

I started this in 2021, after I finally got tired of social networks and deleted most of them. I wanted something slower — a place I actually control, where the only algorithm is what I feel like publishing.

I write more here than I ever did when strangers were counting. Some of what lands on this site is technical, some of it is photos, some of it is half-finished thinking I publish anyway, because thinking out loud is how I figure things out. The rest is just what I'd otherwise lose track of.
