Bobby Gao is a professional in their field. Colleagues describe him as "Bobby was my subject matter expert (SME) for many new IBM Document Manager features during several product development cycles. He was the best kind of SME a technical writer can hope for - with expert knowledge of the product, he produced very informative specs and easily articulated complicated technical ideas when I needed further information. He also took the time to provide thorough documentation reviews and responded to my questions very quickly across the substantial time zone chasm between California and Beijing. In addition to his technical ability, I really appreciated Bobby's good humor and patience. I was sorry to see him leave the team but not surprised that his expertise and active dedication would lead him to exciting new places."
