“Simplicity
is prerequisite for
reliability.”

Edsger W. Dijkstra

i make stuff — robots, web apps, physics simulations, home servers. mostly for fun. sometimes it even works on the first try.

about

hey, i'm leotrax3d. i like building things — hardware or software. if it involves a soldering iron or a terminal, i'm probably already interested.

right now i'm working on a robot arm from scratch, managing a homelab that's gotten a bit out of hand, and occasionally rendering marble runs in Blender just because it is satisfying.

i contribute to the 3D printing open-source community and try to document things properly — so other people do not have to figure it out the hard way like i did.

most of what i build starts as "this probably won't work" and ends up running in Docker somewhere.
