My expertise is in creating working systems, be it analog, digital, or other.
I have experience with C++ and real-time embedded systems (eCos, VxWorks), (ARM, 68k, x86, PPC) as well as with Python, MyHDL, FPGA design, and electronic music synthesis, digital and analog electronics, and RF.
Also, I have many interests, including music, philosophy, and all the sciences.
