Donny Ouyang, CEO @ Rayku (Canada)

I have more feedback at upwork.com. At upwork.com, however, I have some negative feedback also because sometimes I make mistakes :) https://www.upwork.com/freelancers/~01c244295f3ab02a27
Note that I no longer work via upwork.com and other freelance plathorms, even though I'm present on them. I prefer to work directly.
