Hi, I'm Gigi.

I'm a bitcoiner and software engineer, writing words and code for Bitcoin. My first book, 21 Lessons, is one of the most recommended books among bitcoiners. I launched various projects in the bitcoin space and am currently working on my second book, 21 Ways. My main focus is on privacy, security, free software, and education.
