Hao D. is a DevOps Engineer. Colleagues describe them as "Hao is a passionate Coursera learner and fan who volunteered to be TA for several courses and also one of the earliest members of the Chinese branch of Coursera's Global Translator Community. He's taken many courses on Coursera and tries to learn all sorts of new skills from any resource he can find. Plus he's eager to apply those skills and share with others. I was deeply impressed by his devotion, efficiency and sprouting new ideas. His positive energy infected other volunteers and was key to our community's growth. "
