Guten Tag,
I will continue in english, as although i can understand some german, i don't understand enough to be able to fluently read/write it.
First of all,please allow me to introduce myself. I'm Sargon,a 29 years old web developer with more than 10 years of experience in programming.
If you'll take a quick look at my profile you will notice my perfect 5 stars rating out of 235 projects with a 97% percentage of completed jobs.
That along with past client comments regarding my performance i believe will give you a rough picture about my skills.
Now, if you're interested in my offer, just let me know, i have a lot of joomla experience, so i can help you with the upgrades you need.
Thank you for your time,
Sargon
