Leadership Philosophy
Great engineers become great leaders by shifting focus from code to people. I spend time understanding what blocks my team and removing those obstacles. The goal isn't to be the smartest person in the room - it's to make everyone else more effective.
Teams should own their decisions and results. My job is creating the environment where they can do their best work without waiting for approval on everything.
