Having worked with lots of developers Roberto is by far the best I've found so far. Gave him a list of tasks and he completed them all in very quick time, any issues he was happy to take a look at and overall it was a really easy and straight forward process working with him. Will definitely hire again and couldn't recommend more highly.
