I engaged Tony for an initial mission on the Skipcall scope and frankly, it was a very good experience that led to ongoing collaboration. He is autonomous and managed a subject from A to Z without me needing to follow up. He's also rigorous, everything is delivered clean and on time. He integrated well with the small team and the pace. Very good communicator too, we always know where things stand, no grey areas. And what really makes a difference is that he doesn't hesitate to challenge ideas that don't hold up. This pushes the project forward. I recommend him without hesitation.
