Learned embedded programming in school.  At work, I programmed CC2510 8051-based system on a chip for wireless remote control transmitters and receivers in a pseudo-mesh network.  In free time, wrote a cryptographic random number generator for Arduino that was adopted by others and has since evolved into the Entropy library:
