Hello,
I am an OS X and Windows system developer. I have created a lot of applications that interact with the hardware, among which are a Power Meter devices controlling software for Windows (controlling USB/LAN and WLAN/Bluetooth devices from within the application, reading measurements, building graphs of power consumption, analyzing statistics, etc), a wrist altimeter driver for OS X (a usb cdc device), printer drivers (usb printers with a specially designed protocol).
I can design a modular architecture, so that the GUI and the communication logic parts are separated for making future adjustments easier. My code is pretty "clean" and well commented.
I also have experience with iOS development.
I couldn't find the pdf you mentioned (i believe it didn't attach), and my bid is pretty "random" as I couldn't estimate the size of the project. Could you send me a more detailed specification?
Kind regards,
Middaynick
