I would describe myself as an 'observer', a 'bystander'. Scrum master sounds like nightmarish alter ego careerist of me in a parallel universe.
Scrum Master
You provide guidance to the team, which is otherwise self directing. Scrum masters help teams understand the value of their work to the business and users and clear the way of obstacles. Not a manager but a servant leader, you foster collaboration rather than dictating to get the job done.
