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.

    “Li did an excellent job programming a significant portion of a large, difficult project on the stm32f4 discovery board. He kept very good communication with us, giving us almost daily updates, and he was able to solve problems on his own without our help. Li was extremely professional and gave us additional help and advice beyond what he was asked to do. He has my highest recommendation.”
