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!

Very fast, nice and helpful. Alessandro took the time to explain me the reasons for the configuration he did and I really appreciate it.

xsandro knows his stuff. He is very good. He knew exactly what I needed and recommended me other things I had not thought of and included it in the budget. I will definitely use him again as he is that good. In fact I have just re-hired him for more work. I have used many freelancers on here and he is by far one of the finest freelancers and is extremely knowledgeable in his area of expertise.
