Hello Mr. Christopher Diez,
I am an expert PHP and JavaScript developer with 6+ years of programming experience. For the last 3 years I am mainly working on Shopware projects, and have a huge experience in both frontend and backend development. I don't know German language, but I always use google translate, and did not have any problems with clients yet.
I am looking for a long term work, and can do a support of a shopware shop for both design changes and plugin development. I saw that you are using Shopware default theme for you shop, but if you want I can also create a completely unique design for the shop.
Hope we can work well together and hope to hear from you.
Thanks,
Arman
