    “xsandro goes above and beyond what you ask of him. He truly is a professional amongst the rest of the people that we all see on Freelancer who call them selves experts or professionals. He is knowledgable in his field and wise in that he won't just do what you ask of him he will guide you or recommend you things you would not have seen. He has helped me successfully implement Google Apps and Zendesk. I will definitely hire him again. And I recommend him to anyone. I just hope my recommendation doesn't hurt my chances of re-employing him in the future. 11/10 he's that good!”
