I’ve admired Sean’s work for years — he’s sharp, approachable, and one of the most collaborative colleagues I’ve known. Sean is so sharp I feel like I’m merely watching him from a distance, and trying to keep him in eyesight before he disappears into the horizon. That’s not to say he isn’t one of the most pleasant and approachable tech experts I’ve known, because he is. The fact is I consider it a company perk to work in the same organization as Sean.
