Frankly, I highly recommend him. Besides having all the technical, human, relational skills, etc., he had a brilliant idea several times that allowed us to solve certain problems, thanks to a different perspective, and I would even say a bold step aside. Ultimately, he is very professional and very helpful, and above all very smart...
