Hi there,
I have more than 25 years of experience just in C and C++ over linux, bsd, solaris, qnx, freeRtos, OS/2, DOS or windows in backend (distributed or not) working for very important corporations, so I think I can help you with this stuff. Right now I have some free time to do this.
And I have worked a lot with device drivers, so I think I can help you with this stuff.
Please contact me.
Thanks
