  • image of Andrew W. Arduino programming $200.00 AUD

    “I really don't recommend to hire this freelancer because he doesn't have any piece of knowledge and I'm pretty sure he is just wasting his time using freelancer. I hired him for my project, and he is so lazy and useless guy. Even he did not complete the project , he refused to refund my money until I disputed him on the freelancer stuff. I'will not hire him again and I DON'T RECOMMEND TO HIRE HIM FOR ANY TYPE OF PROJECTS.”
