I'm Michael Kohl, generally known as citizen428 online. I
started programming in BASIC on my Commodore 64 and am lucky
enough that I could turn my hobby into a career: over the
years I worked as systems engineer, software developer,
penetration tester, CTO and IT journalist. I'€™m currently
self-employed, so if you have an interesting project to talk
about, please contact me at citizen428 at omg dot lol.

I'€™m also very interested in community building. I previously
ran the Lambdaheads functional programming user group in
Vienna, and am currently involved in Bangkok.rb, RubyConf
Thailand, as well as PyCon Thailand.
