Christoph Daum (@apermo) – WordPress user profile

WordPress Origin Story

I started of doing mostly TYPO3 when my good friend Hendrik Luehrsen @luehrsen talked in the highest tones about WordPress. Later during my agency days, I started working with WordPress, and in 2012 I attended my first WordCamp in Berlin, which was called WPCamp. On my second WordCamp in 2013, I met Robert Windisch @nullbyte, well and for everyone who knows Robert, this is all you need to know. Since that day, I’ve only missed a 3 WordCamps in Germany, I became founder and host of my local WordPress Meetup and I’m part of the “usual suspects” to buy a WordCamp ticket on release day.

Since 2014 I call myself an in-house developer for WordPress, doing WordPress as a full-time job. During these days I’ve dug very deep into multiple areas of the WordPress code, found a few bugs, suggested some improvements and the best is yet to come.
