Hey, I'm Leonardo Romero.

Creating software to make life easier.

/ about

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.

The drafts exist. They just keep winning every internal meeting.
