My name is Sebastian Helzle and since 2007 I'm a freelance web developer living in the beautiful city of Karlsruhe in Germany.


I like reading, trekking, talking with people, traveling and enjoying the good things in life like good food, wine and beer.


A lot of my projects are based on the open source TYPO3 CMS. Since 2013 I'm also involved with TYPO3 Flow and Neos. I already took parts in a few code sprints for TYPO3 Neos including the release sprint of version 1.0 in december 2013 in which I contributed a lot of the included demo site.

I have also been working with Javascript for many years now and created several jQuery plugins for customer projects and also open source ones you can find on Github. And in 2013 I also started working with AngularJS which I like a lot.

Since 2012 I'm also doing a lot with continuous delivery (Jenkins, Gitlab, Selenium, TYPO3 Surf), DevOps (Chef, Vagrant).
