Production

I was a full-stack software engineer and team manager. I have lots of experience in successful Internet product publication. My experience spans nearly all Internet-related software systems development, including cloud computing, distributed systems, machine learning systems, applied machine learning, operating system, and mobile applications. Business domain: cloud computing, automotive intelligent system, autonomous driving, smartphone, Maps/LBS, games, etc

  • Tencent Cloud. 2017-2018
    Worked on business-oriented cloud computing solution; led a team to develop the 1st generation cloud computing solution for the automotive industry.
  • Tencent Venus Distributed Machine Learning System. 2016-2017
    Worked with Shengping Zhou (now CTO@AlphaCloud), developing the large-scale distributed machine learning system for MIG, Tencent. This platform supports various machine learning algorithms and models, including, LR, SVM, GBDT, DNN, etc. One more thing: I have to highlight that one module of Tencent Venus contains the first practice of federated learning system in China, even in the world, earlier than Google FL. At Tencent, we supported vertical federated learning infrastructure for WeBank to model Tencent social network features into their financial models.
  • Tencent Location Data Computing Platform. 2016-2017
    worked on streaming data mining systems and algorithms; this platform contains billion-level daily users; I learned the entire system architecture and related real-time data analytics algorithms.
  • Speech Recognition and Natural Language Processing for Tencent Automotive Operating System. 2015-2016
    This project inspired me to explore ML models, algorithms, and systems; deep learning is very fancy that year; we developed a deep learning model compression engine for our product (at that time, TensorFlow Lite is not released yet)
  • Tencent Games: a Pokemon Go-like Mobile Game Engine 2016
    worked on Unity3D and C++ -based game engine; this is a cross-group collaboration, very fun; I learned a lot of engineering and production culture at Tencent Game.
  • Tencent AI in Car (also called Tencent Automotive Service). 2014-2016
    I was leading an operating system team; worked on the embedded operating system (Android/QNX) and related back-end cloud services, including more than 10 applications and system core service, such as WeChat MyCar, Tencent Maps, Tencent Music, Tencent Video, etc. Please watch the video below to have a taste how Chinese Internet companies advertise their products:-)
  • As a Team Leader, I Developed the 1st generation of Smartphone Navigation SDK, Application, and Service in China (Baidu Navigation SDK). 2012-2013
    Baidu Navigation SDK, Application, and Service is a cross-platform (C++/Java/Objective-C) engine that requires computer graphics (OpenGL ES), routing algorithms (A*, CH), offline and online data compiler and networking service (Hadoop; C++/PHP backend), complex navigation UI message state control and dispatch, cross-platform, layered, and modularized complex system design. I am familiar with all of these core modules.
  • As a Software Engineer, I Contributed to the First Generation of Huawei Smartphone. 2011-2012
    The picture below shows Huawei Ascend P6 (Emotion UI)
