To make contacts offline you still need a cool business card. To show your specialness, I recommend to avoid ready-made card templates.
Instead, create your own minimalist design. If you don't have a logo, do it without a logo. That's the cool thing about minimalism - put as little as possible on it. Take the things away and you're on the safe side
Minimalism in Europe is a sign of good style. A business card with lots of information is considered as cheap. The same trend "as few as possible" applies to representing your skills. Even if you really good in a bunch of technologies, such a "specialist in all areas" would be considered as rather suspicious by Germans.
Minimalist design signals to your employer or your client or business partner that you know the latest trends in western Europe and that you have particularly profound knowledge and experience in few technologies. That looks trustworthy.
Note: ask Google images for "minimalist business card" and get inspired. See the screenshot above
Write your first name and last name only. Leave out all the middle and additional names.
Example: Chintan Patel. Such a name format is clear and understandable to the German eye.
Enter your profession as briefly as possible.
This section is optional. But if you can't resist the temptation: enter here 2-4 (maximum 5) technologies or frameworks which you master better then others.Tip: instead of entering fields of expertise I recommend to enter your link(s) to Github and Linkedin OR XING profile. If you have your own website - even better!
Job applicants with an own website are rare, so your own URL (even just onepage website) would be a one more detail to demonstrate your individuality (s. Individualism chapter below).
The sense of entering an URL on your card: you can't change anything on your card as soon as it is printed on the paper. But you can change any details of your expertise on your webpage (Gifthub/Linkedin/XING).
It is advisable to avoid decoration completely. Or at least reduce it to a few lines. If you are not an artist, your business card serves only one purpose - to provide your contact information. You should show creativity in solving problems in your field of expertise.Tip: Print your business card just on one side and only in English. Exception: However, if you speak German (even if only at A2 level), you must mention it on your card because it is a huge advantage for you!
