My name is Mingshi Wang, a senior software engineer at Uber. I am currently working on Michelangelo - an internal machine learning platform at Uber - to help teams across the whole company to solve their business problems using cutting edge machine learning technologies. I am passionate in developing systems that reliably distribute the most commonly used open source machine learning frameworks at Uber's scale. My experience with Michelangelo has been exciting as I see Michelangelo grows from an immature system to a full fledged infrastructure of many of the most important projects at Uber. These projects includes driver pickup time ETA, Uber EAT restaurant ranking and the autopilot system for self-driving cars, to name a few.
