C/C++ Programmer with STM32f4 experience - repost

We need someone to help us develop an mp3 player on a STM32f4 board using C++/C. Specifically we would like someone to implement the functionality of playing mp3s from the board and apply phase vocoder technology to it based on accelerometer input to match song beats to back and forth motion. Our previous engineer has gone missing, so we need someone to step in and finish this project quickly. We would like this project to be done by the end of this month. Please contact us for further details.
