Hey, I'm Leonardo Romero.
Creating software to make life easier.
A bit about me before the links.
Open source, by default.
I build free and open-source software because not everyone can afford a license. If a tool helps me, I'd rather it help the next person for free than sit behind a paywall.

A varied background.
I've spent years in study groups, sports teams, video-game guilds, and music bands. Working across those communities taught me to read a problem from the outside in and attack it from the angle that actually moves it.
