responsible for realtime embedded system for smart light (patent pending) for racing motorbike which keeps lighting area level even if bike is tilted at high speed especially at hairpin curve. Tight time requirement, quick response. Because of life critical system DO-178B level A practice is applied. Test system is written in Python for in-house use. C++

NEST team. responsible for the development/maintenance and execution of test automation for testing 200+ devices at lab every 4 hours. Half of the system is open source. The rest is Google proprietary code which depends upon open source. add many enhancements, fix bugs. complicated build process. Refactor test code so that the same functionality is written in the same syntax even if the actual device command is different. Device communication is done the same way where difference between ssh, ADB, etc does not show at the test code. Python 3. Familiar with Google development tools/environment.

Linux, TCP/UDP/Ethernet. C++

Migrate Python2.7 to Python3. It is big, tricky, time consuming project because

there are 2,000 differences between Python2.7 and Python3.

Huge number of Python2.7 source codes.

depends upon a lot of third party libraries. Some of them changed naming, & interface. Some do not support Python3.

many internal libraries. Some of them are not migrated, not supported. Others changed interface.

Develop tools to help other developer : memory usage, performance inside Android-like device.

Also port 3rd party tool to the devece : systemtap, SPEC benchmark.

C11, C/C++, Python

Designer of EyeScore (Signal Integration tool) which collects many coefficients for every link for statistical analysis such as BoxPlot, ScatterPlot, Standard Deviation. designed to support existing and future routers, also can adapt other tool/hardare. Multi threads, 12 hours to 1 day runtime. store at Excel.

Symptom Based Analyzer to solve any/all problem at router by combine/integrate many fragmented tool.
