PROFESSIONAL EXPERIENCE

Senior Software Engineer, General Motors

Oct 2015 – present
General Motors Canada, Markham, ON
Projects: Android-based vehicle infotainment system
– Responsible for software development in Android framework for phone projection, connectivity, and network management features, following Agile/Scrum process (GIT, Gerrit).
Programming languages: Java, C++.

  • Fast prototyped Wireless Android Auto (WAA) feature before 3rd party dependency was ready. Saved 3 weeks’ time in project schedule.
  • Designed and implemented Wireless Projection Service in Android framework to support WAA feature: sharing WiFi hotspot info to phone via Bluetooth RFCOMM connection, and starting Android Auto session in WiFi connection following Google spec.
  • Fast learned Apple spec and Bonjour service, and successfully implemented Apple Wireless CarPlay (WCP) prototype using C++ and JNI before 3rd party library was ready. Saved 2 weeks’ time in project schedule.
  • Extended Wireless Projection Service to support WCP feature: Establishing iAP2 channel over Bluetooth and sharing WiFi hotspot info to iPhone, discovering and resolving Bonjour services, and starting CarPlay session in WiFi using Cinemo’s library.
  • Refactored Device Connection Management Service: managing all connected devices in Android including Bluetooth devices, phone projections and OnStar. Implemented the service using Android Handler/Messages, AIDL, State Machine, and Content Provider. Significantly improved the stability, scalability, and maintainability of the service.
  • Worked with software architect to design vehicle network system. Implemented Net Filter Service to manage network firewall rules and data traffic priorities. And maintained Android connectivity system (Connectivity Service, Network Management Service, netd).

Software Engineer, Qualcomm

Feb 2015 – Oct 2015
Qualcomm Inc., Markham, ON
Projects: Android platform development of automotive infotainment system
– Responsible for software development and maintenance of Android display system based on Qualcomm SoC.
Programming languages: C, Java.

  • Actively involved in Linux open source development, and contributed source code to Linux kernel display driver to support 3 displays in Android.
  • Fast learned Android framework in a very tight project schedule, and successfully implemented new feature of multiple apps co-existing on multiple displays, by modifying Android core services: Activity Manager Service and Windows Manager Service.

Software Engineer, Thales

Jan 2013 – Feb 2015
Thales Canada, Transportation Solutions, Toronto, ON
Projects: CBTC (Communications-Based Train Control) system
– Developing train control systems for new subway lines all over the world. Responsible for developing wayside sub-system which is the mission-critical part of the whole system.
Programming languages: C, Python.

  • Designed system using redundant replicas to achieve high availability and high reliability.
  • Developed C programs to process inputs from all replicas and control wayside field elements. Fixed low-level program issues by directly programming hardware registers.
  • Captured CAN bus messages using CANalyzer, developed Python scripts to decode CAN bus messages, and performed data analysis.

Senior Software Engineer, Continental AG

May 2007 – Dec 2012
