When Antonio came on-board for this project he picked things up pretty quickly, but I've been even more impressed by his pace now that he is familiar with our system and database schema. He has been a key asset in delivering this product to the end client. A regular and good communicator, delivering exactly what was asked for rather than getting bulked down with niceties, I would highly recommend Antonio for any PHP development work.
I'm really pleased with Antonio's efforts so far. He's a very capable developer and sys admin, and has bought a lot of skill and ideas to the project. His written and spoken English is also to a high standard.
