Since 1996 I've gained experience in web productions. This page is only a brief excerpt of projects I did so far.

This is a small web project for a Swedish style holiday house in the middle of Germany located in the beautiful Mecklenburger Lakes area. The site features photographs, maps of the surrounding as well as directions and routing. Also included is a an online booking calendar.

In cooperation with the Furtwangen Institute for Business Consulting I've been developing the backend of an
e-commerce website for our client 'Flyerfabrik'. Features include a completely modular image e-catalog, upload facilities as well as an online ordering module, enabling the users to build and order their flyers, posters and business cards online. By integrating the XML Online Tools of UPS United Parcel Service, customers of Flyerfabrik can request shipping rates and even track their packages in real-time.

Plantronics, famous for their state-of-the-art headsets, has recently relaunched its global ecommerce websites. With Addwater I've been working on a kind of "LEGO box", that made this consistent branding experience possible: an implementation guide (i-guide).
Here I've played a key role in forming the i-guide architecture, defining site modules, setting up design and coding rules and guidelines for globalizing its modules as well as creating reference libraries (graphical assets, colors). The design in a modular fashion enabled an ease of international expansion, as demonstrated with the massive global re-launch.

'web.PVDE' is an Intranet application for mining a large brand database and graphically representing the queried data sets. I've been working on the architecture, backend and user interface design and data conversion of this application during my second internship semester at Addwater, San Francisco.
Filtered survey results of 2500 persons and 800 brands are now available to Addwater brand strategists through this data mining tool, saving hundreds of hours of manual analysis and revealing new valuable patterns.
Lastly, I created real-time graphical chart visualizations and structured queried calls to overcome complex analytical steps to guide users through easy-to-use business logic.

The Wells Fargo Bank was introducing new web-enabled ATMs to their clients in North America.
The extraView is a web application for reviewing, commenting and approving ATM screen designs online. I was the lead developer in charge of conception, architecture, prototyping, UI design and implementation of the extraView.
This tool, developed for Addwater, San Francisco, optimized the design production workflow and client feedback channel and set the groundwork for the next generation review tool.

I've been working intensively on this global treasury intra-/ extranet during my first internship semester at Pixelpark. Special features:

• high-end CMS (based on Vignette StoryServer)
• unicode support (German, English, Japanese)
• personalized user interface
• integration of Reuters investor services
• xml content exchange
• one2one chat solution

In addition I was involved in the customer support for New York, Düsseldorf (GER) and Singapore as well as in technical conception concerning secure LDAP structures. Managed a team of software engineers.

Again at Pixelpark I was working on relaunching the WACKER group website, a globally active company with a mix of chemical and semiconductor operations.
My work included in-depth evaluation and comparison of different content management systems as well as developing the cross-browser (including NS3 and IE3) navigation.

What started as my first dynamic website project in 1997 for the local Protestant Youth of my home town has evolved towards a virtual community platform. Most members come from Germany, Austria and Switzerland.
Features of cat-net include chatrooms, discussion boards, online polls as well as a CMS. Highlights so far were especially VIP chat events and the presentation at CeBIT HOME.
A popular as well as controversially discussed feature is an interactive x-mas photo story, featured at search engine specials, newspapers and various radio stations already.
