Hello, I am hardware/software engineer, focused on hardware designing: components choosing+software simulation(LTspice,Proteus)+ making sch/pcb (Altium Desighner/ DipTrace)+writing firmware(AVR , ARM (STM32 ATSAM3S) + FreeRtos). My experience in this field more than 7 years I could also write high level software on C# for communication with devices by RS232/Radio/USB etc. I'd also have expereance in development of AC-DC LED Fly-Back drivers and as my hobby - in amplifiers(LM3886/TPA3116) and music DACs (AKM / AD1955).
