Throughout my life I worked a regular job no more than 3 years. I am running two consultancy/engineering companies - one in Norway, the other in Lithuania.
I have been working with cutting edge technology all my career. Ranging from Medical devices, very low electrical signal measurement to high power X-Ray generators. Very high operating temperature electronics for Oil&Gas sector to advanced electrical vehicle electronics and car hacking. Did I mention advanced soil property measurement systems? Electrical equipment that is operating in the sea with depth of up to 400meters?
