Hello sir,
I have already done scrapping and crawling for many online stores like amazon,ebay,aliexpress and many other. If the ip is blocked after continues hitting then i have wrote an algorithm that uses proxies to scrap.
I have almost 4 years of experience in. Net c#. And believe me i am very good at it.
I am available on skype and whatsapp all the time for better and fast communication. Looking forward to work with you.
