Excellent mission! David was great from start to finish. He did much more than the single day of work that was planned. He is serious and professional, while also being friendly and reassuring. I wasn't an easy client as the mission was stressful, but he handled it. I wouldn't hesitate to hire him again. He also has a bit of a psychologist's talent ;) A big thank you and see you very soon.
