Hello
First of all I want to tell you that i already made 2 csgo websites a gambling website and a penny auction.I want to mention that one of the websites is made after stem uploaded their policy with steam mobile guard(now you must to confirm all trades from the mobile phone)but i can do that from node.js .
so i think that is advantage for me in front of others freelancers which worked before with steam api.
For more details contact me in the chat and we will discuss more.
