About

Gabriel Palmisano

Hi, I'm Gabriel.

I live in Bari. I've been writing code since I was a kid, because I wanted to see how far a technology could go.

Maps came later and never left. Every time I see one, I ask myself: which map is that?

Today I'm a Mobile Developer at EBWorld, and most of what I build ends up in the hands of people who work in the field.

I like traveling. That helps, because I also like speaking at conferences.
