Hello Aviv,
I've got three years of experience with dropshipping stores. I used to fulfill orders both manually (finding a listing on aliexpress and placing orders) and automatically (looking through orders that had been placed and paying for them if no issues found. These orders were placed either by nimble or oberlo). Also, I have experience in creating product listings in Shopify, keyword research, customer support (emails, Facebook messages, etc.), disputes handling (PayPal disputes, Shopify chargebacks, aliexpress disputes). I'm available full time.
In regards to the list of questions you posted above, see below:
1. English level - C1 advanced;
2. import products from aliexpress to Shopify - I did this kind of task before. I'd imported a few thousand products from aliexpress to Shopify using oberlo app, all products were categorized by tags and were added according to the keywords provided;
3. fulfill orders - I have experience in finding good listings for products on aliexpress and placing orders;
4. customer service - I can do emails, messages, live chats;
5. Social media - My only experience with social media is replying to comments and messages on Facebook;
6. graphic design - only in terms of product listing creation;
7. Shopify - send me links to Shopify stores you managing right now - I don't have any projects that I'm managing at the moment. I can give a few links to the websites I'd been working with.
Feel free to contact me for more details.
