I am Christof,

a French-German Software Engineer based in Barcelona, Spain.

Stuff I am or was involved in:

Foodstyling Ballschuh

July, 2015

Wordpress based website for a Hamburg based food-stylist.



January, 2013

The german pendant to pinkstinks in the UK.
Pinkstinks is a campaign that targets the products, media and marketing that prescribe heavily stereotyped and limiting roles to young girls.
I'm in charge of any type of adaptation, change or new feature.


The Open Song Project

November, 2012

The Open Song Project is a collaboration between the renowned Danish Electro Rock Orchestra Spleen United and Nokia. A web special to promote the arriving of the new Nokia Lumia 920 was created in collaboration with RWATGG. I was in charge of implementing the PHP/MySQL backend.


Tofumanufaktur Berlin

September, 2012

This group of young enthusiasts make their own tofu in Berlin.
To support them, I created a web page to promote their products.
Applied technologies: PHP-backend with CodeIgniter, HTML5, CSS3, JavaScript (JQuery, Google Maps API, ...) and a bit of MongoDB.


Schwarz&Bold Website

July, 2012

The new web presence for the healthcare advertising agency Schwarz&Bold.
PHP-backend with CMS, HTML5-frontend, JQuery, mobile adaptations, social integration...



January, 2012

For this project for Kaspersky we created a special web page to promote their new product KasperskyOne. There was a lot of JavaScript involved and I coded my first (productive) "social features" (Facebook, Twitter).



Juin, 2011

A new page is born! technical... philosophical... based entirely on HTML5, CSS3, JavaScript and a bit of PHP on the backend side. A playground for new features! And this is just the beginning...


Kinect & Processing

January, 2011

We used the Kinect for XBox360 device, took its raw 3D video output, transformed it with the open source programming language Processing and were able to render some pretty amazing images/videos! And yes, we had a lot of fun :)


Sennheiser Mobile Music

October, 2009

Marketing special for Sennheiser Communications. Product: Mobile Music.
Again, our tellMe-Framework enabled us to quickly implement all features. Flash-frontend. Smart backend :-)



September, 2009

We just finished our first multitouch device, codename: Cyclon! It is an optical system (not capacitive like the iPhone), which is based on infrared LEDs and a video projector and measures a total of about 2 * 2 * 1.5 meters. Touching is strongly welcome!


Mousse-T Website

August, 2009

For the new Mousse-T website, we integrated our tellMe system: a gateway between Flash (ActionScript 3) and PHP. tellMe is based on AMF (Action Message Format) and enabled us to build a system that allows users to record a video message on the page, save it in a gallery and send it to a friend. tellMe was used for nearly all projects which implied a strong backend for the Flash frontend.


iceAge 3: Dawn of the dinosaurs Website

Juin, 2009

For the customer Pritt we realized a website that combined the new Iceage 3 film with the products from Pritt. Implementation in 3D: Website in Papervision and ActionScript3, contest with FileUpload and Gallery. Typo3 support and multilingual XML files. International launch.


WMF Coffeewall

April, 2009

Programming of a web special for the launch of the new WMF-One coffee machine. Theme-Generator: an area of coffee machines becomes your drawing board - the painted images of the users can be sent via email, downloaded and stored in a gallery. Implementation in ActionScript 3, Papervision 2.0, PHP


Google as File-Search-Engine

July, 2007

With proper search queries you can use the Google search to find files like in Peer2Peer download programs. It makes use of parameters in the search string. The specified parameters used here are:

  • inurl: Web pages containing the search word in their Web address. This may also occur in subdirectories.
  • intitle: Web pages that have one or more of the search terms in their title.
  • filetype: Results on certain file types.

Check it out:



I'd be glad hearing from you :-)
