I am a Linux kernel engineer, and have 6 years' experience in Linux kernel & Linux driver development. Therefore, I'm very skillful in C programming.
Also, I am a Bluetooth engineer, have developed many Bluetooth products, such as Bluetooth PTT(Push to talk), Bluetooth headset, Bluetooth speaker & mic, Bluetooth video recorder. Because the Bluetooth host is embedded device running Linux OS, so I am very familiar with BlueZ protocol in Linux.
I am a skilled DSP worker too, and had developed many vocoder arithmetic which are based MBE.
