Allow me introduce to you my teacher, guru, mentor — Jiaxu (“it’s like cashew with a J”) She. For the past 16 months or so he’s been teaching me many lessons in software engineering and product development. I’d like to share some of them with you in a series of small, short mini-stories. In these vignettes, let us talk about MVP’s, product differentiation, user experience, displacing older technologies, and much more. I will draw upon my own experience working at AQR, on pandas, DataPad, and at Cloudera. And when I inevitably start to get boring, I will make it up with baby pictures.
