Fabian Steeg — About

I’m a programmer from Cologne, Germany. These are the things I’m building, sharing, and learning.

Most of the software I build is public on GitHub. For general information and links see fsteeg.com. My recent private projects include setting up an indie micro blog (2017), Bit.Buster, a minimalistic iOS game (2016), and Blockcheck, a blockchain explorer (2014).

Recently learned about Design of Computer Programs and Python from Peter Norvig and others on Udacity (2017–2018). Completed courses on Reactive and Functional Programming in Scala from Martin Odersky and others on Coursera (2012–2013).
