I work on experimentation at Tencent in Auckland. Built the experimentation models now used in 9 product decisions a quarter. Cut the time to a trustworthy experiment readout from 3 weeks to 5 days. Previously at Alibaba Group. Most at home with A/B testing and Bayesian statistics. Yoga every morning.
