Got my first job on UpWork, and I think I got scammed already :(

What happened?

I started chatting with a guy, he needed a quick fix for his app. I didn't even notice that I wasn't employed yet, he just sent me a message. After some talk I solved his problem, and since then he didn't even log in. Guess it's also my fault

🙁 well consider this lost fees as the fees for lesson.

A lesson about How to Deal with Clients.

Yeah, never offer any help on UpWork until after the agreement ($$$) is finalized.

Next time leave a backdoor before you negotiate

Don't leave backdoors. Upwork has a great system which prevents people from scamming. Simple tip: if you get paid by milestone don't start work until they activate(pay for) the milestone, if you get paid by hour, work only with clients who have payment method verified.
