Not take my word for it, do you even understand what giving a link to your profile on Upwork means? You can see what they worked on, how much they charged for and most importantly what was the feedback the client did. And I am not talking about jobs with 200/300 USD range pay, I am talking about jobs with thousand of hours and tens of thousand of dollars as payment with more then six months of continuous commitment to them AND at the end of those jobs my clients praised me while giving me 5 stars. That's what I meant with verifiable track.
