Who is me?

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.


Since 2007 I'm working mostly as freelance consultant for web projects, but I also worked as developer, Scrum Master and Product Owner in agencies.

A lot of my current projects are based on the Open Source CMS Neos. Since 2013 I'm involved with the development of the PHP framework Flow and Neos which is built upon Flow. 

I was also working many years in TYPO3 projects and helped in building several big websites.

During all those years I have also been working with Javascript and created several jQuery plugins for customer projects and also open source ones you can find on Github. Now I'm working on extending Neos with React.js modules.

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