Hello, Sir.
I can speak in English freely.
As I'm a Senior Embedded System engineer, I have rich experiences in many embedded systems development and programming.
Especially, I had designed many GPS projects using various Micro-controllers such as FPGA BGA, STM32, Arduino, Wifi/BLE modules and GSM/GPS/GPRS/GNSS, various sensors.
Also I can develop the firmware and windows & mobile apps for the embedded systems.
So, I would like to work this project with you.
Best regards.
