My name is Federico Builes. I’m a software enthusiast who’s been playing with these things called computers for about 20 years now. Born and raised in Medellín, Colombia.

You can find my open source contributions on GitHub.

Some of my online projects include (which has been called a "fine piece of work" by many copy-pasters) and Carnival9 (a short-lived experiment).

In 2017 I wrote a book called "Bitcoin on a Napkin" in collaboration with OV. You can find it on Amazon.

A "Talks" page is coming Real Soon™. In the meantime you can find my slides at Speaker Deck.

stopmakingsense was a blog of sorts.
