Cocky. Confident. Brash. Brilliant. Bhavish Aggarwal is all of these. And he is more. At first glance he is a man on the cusp of midlife. His pitch-black hair seems to have been brushed back aggressively, revealing a growing forehead untouched by frown lines. He loves dogs. They are the only beings with unbridled access to him, in his office, in meetings or at home.
