EXPERIENCES

1)May 2007 to DEC 2016

Design Engineer, Location: Portland OR

I designed products and provided total solutions to the following companies:

1)China Hewlett-Packard Co., Ltd

2)Shanghai jumo technologies

3)shanghai Bestwin technologies

4)Wuhan junxin Technologies

5)Wuhan xinmingda technologies

etc

Most of products were designed by myself alone, so I had to design firmware, hardware and software including layout PCB, soldering, debugging, testing.

1.Touch screen pad with DES,3DES encryption: This product is IPAD-like device with 2.5G WIFI, using Cadence PCB tool for hardware, using C and assembly based on Cortex-M3 for software, and assembly PCB. Finally providing a sample product and all design document to shanghai Jumo technologies.

2.Hearing aids with signal processing: Evaluated which platform, such as ARM or DSP or FPGA, is the best for the requirements. An FPGA( Xilinx SPARTAN 6) was used for this product. Designed hardware using Cadence tools; software using Verilog.

3.Electronic acupuncture therapy device: This product is a medical device. I worked with therapy Doctors and transformed their demands into

technical requirements; I designed the firmware and software based on Cortex-M3 with bluetooth to communicate with smart phone. I designed the communication protocol and Layout PCB using Cadence, Allegro.

4. HP thin client software : This is a commercial software China Hewlett-Packard Co., Ltd. (DES,SSL,AES,Telnet,TCP/IP are included) which runs on windows.

5. Bank terminal equipments: This products were designed for shanghai Bestwin and China Hewlett-Packard Co., Ltd. I designed all of components. This products include key-pin, Magnetic reader and writer, UART extension-er, Printer controller etc.

6. 350Mhz remote controller: This product is kind of like smart switch which include Wifi to connect internet,350Mhz to transfer sensor status.

2)Bell XUNJIE(BELL LABS) Technologies CO,. LTD – February 2002 to April 2007

Design engineer

Bell XUNJIE was funded by the city government of ZHANG JIA GANG based on a strategic cooperative agreement with Bell Labs, Lucent technologies

1.High definition television decode chip and reference system: pre-silicon validation .Worked with BELL LABS engineers.

2.MPEG-4-Over-IP Surveillance System: designed firmware, debugging and testing. Layout PCB using Cadence, Allegro.

3.Bluetooth module: Designed the firmware, a part of software, debugging and testing, Layout PCB using Cadence, Allegro; solved signal integrity problem.

3)HANBO (STAR) Technologies CO.,LTD - October 1996 – February 2002

Embedded engineer Shanghai

designed firmware

1.designed bank equipments like PIN-pad and magnetic stripe read-write devices using 8051 with c and assembly language and layout PCB

2.designed printers and printer's controller using arm MCU with c language

3.Layout PCB using Cadence, Allegro and Protel

4)KEJIAN Technologies CO., LTD - September 1994 – October 1996

Design engineer Shanghai

1.Designed two generations medical machines using INTEL 80X86 platform with c and assembly languages and layout PCB using protel and PADS designed sensor circuits, motor control circuit and firmware, hardware.

5)GUIZHOU Institute of Light industry - July 1991 to July 1994
