Embedded software and DSP developer since 1985.
Experience ranging from developing sonars for submarines, through earth stations for satellite communications and miniature, extreme low power satellite radio devices to road traffic controllers with all of the safety constraints that this involves.
I have used many generations of processors from the new-fangled intel 8086/8087 combo through 8051, 80x86, DSP56K, MSP430 to ARM-Cortex and MIPS embedded processors but always with less than 512K of memory.
