Is there adult companies that needs php programmers in Munich, Germany?

do you have a link to your mainstream work?

I don't have too much mainstream work, but I can provide some old examples:

Kuponexpress.pl
It's Polish Groupon clone, with departments in 6 cities (Tychy, Wroclaw, Gdansk, Szczecin, Warsaw, Poznan). Now they seem don't have any coupons, but in 2011 they had many contracts and hundreds of coupons available.
I was hired on dual position, php programmer and tester. These times I was the only programmer working on this project.
Mainly I was fixing and modifying the scripts for their needs, adding new functionality.

NXT-Event Yorkshire
British company that organize gaming tournaments in Yorkshire area.
I met owner of this company in 2010 and I was doing most of php coding for his business.
Beside this website, I was also working on tournament-specific websites with tickets pre-order paid by PayPal.
He has also game development studio, I made him the website too (with design): http://nevonix.com/

I have also some certifications passed:

Soon (next two months) I am planning to get Zend PHP5.3 cert, and until end of the year Zend Framework and Oracle MySQL certs.

Next moth I am looking for job in local mainstream companies, so when I come to Munich next year I will have something more to show.
