About

Hi, I’m Yexi. A father and an engineer.

I’m currently working at Roblox Corporation, building the recommender systems to bring the users with personalized experiences on the Roblox platform.

Before that, I worked at Uber Technologies Inc., Facebook, IBM T.J. Watson Research Center, and Microsoft Research Asia, working on various machine learning related projects/products such as News Feed, Friend recommendation, data mining applications on improving cloud system management, and Office user behavior mining.

Besides, I also engage in the Open Source community as a member of the Apache Software Foundation, where I am a PMC member and committer of the BSP-based distributed computing framework - Apache Hama, mainly working on the distributed machine learning module.
