I am an electical engineer, I work as a C# and PLC developer. I use Raspberry PI every day (for my hobby and for freelancer jobs).
I was dealing with a different type of embedded devices (like PLC, Raspberry PI, STM32Discovery board etc.) and made for different goal (home automation, HVAC controlling, for middleware applications). My favourite development area is the embedded webserver (remote controlling) and the home automation. I made a lot of interface between different systems (like between home automation and mobile services etc.)
