My name is Federico Builes. I’m a software enthusiast who’s been playing with these things called computers for about 15 years now. I live in Amsterdam where I work for a company called Catawiki.

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).

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

You can see the music I’ve been listening to lately in my page.

stopmakingsense is a blog of sorts.

I keep a list of tech ideas that I’d like to explore some day.
