You have found the master site of Niels Hoffmann's online identity. I am a Berlin based Ruby on Rails and iOS developer. You can find my CV on linkedin. You can also find me on github, follow me on twitter or just contact me.
I build things on the internet and sometimes release them. I am the author of Blabber and Fandango.
When I am not hacking on a computer, I play electric and upright bass in a couple of bands, but that's a different story.
