Web Professional *

My name is Lars Kroll. I design and build websites for more than fifteen years. From 1999 to 2014 as co-founder of the agency W3 WERK.

Since this year I present myself under www.lars-kroll.de with new projects.


Working as a Senior Consultant for the EXXETA AG, Stuttgart

2015 to 2019

Since February 2015 I am working as a teamlead UXE for internetstores GmbH, Esslingen/Stuttgart. I am responsible for the development and implementation of designs systems for all of the hybrid apps and mobile/desktop shops like m.fahrrad.de and m.campz.de and so on. Furthere more i take care of frontend optimizations and implementation of projects.

I left W3 WERK at the end of April 2014 in order to devote myself own projects and new challenges. I thank all customers who confided in us for so long.

1999 to 2014 - W3 WERK Internetproduktionen

I was heavily involved with the realization of all projects of W3 WERK. Besides working on the conception I was responsible for programming in PHP / ASP, MySQL, Javascript, and CSS DHTML/HTML5. I also provided training for the CMS W3 Publisher, which I developed by myself.

Particularly noteworthy work:

While still a student, I co-founded W3 WERK 1999 in Stuttgart, Germany. One of the first clients were Seiler & Kunz from Freiburg. For them, we created the online magazine 'Input'. The self-developed editing tool for the website was the base for the afterwards newly designed W3 Publisher . The next job came from Porsche: the multilingual Porsche Worldwide Event Planner . The foundation stone was laid for W3 WERK.

Among the long-standing clients, belongs the German Multiple Sclerosis Society (DMSG) with the Federal Association and their various regional offices. Since 2001 I was instrumental in expanding the websites to the most extensive and important platforms about Multiple Sclerosis.

As early as 2003, W3 WERK was awarded with the media price of AMSEL-Foerderkreis Ursula Spaeth e.V.
