Narrative:

A ground communication error occurred. I started the up both engines and completed my after start engine flows. I kept the right engine in feather to operate the air conditioning in the high pressure mode. We ran an after start checklist. I gave the chocks pulled hand signal. The same signal was given back by the ground operations employee; at the aircraft's nose. I thought the chocks had been pulled and started my taxi. As I crept forward; I saw another ground agent running from under the nose to the left side of the aircraft. This startled me; so I hit the brakes until the worker was clear. I braked within two feet of my starting point. I received no stop signal so I was unaware of employee by the nose gear. Miscommunication must have occurred between the marshaller and I.
