I am a retired mechanical engineer who have been working most of my career at a nuclear power plant in Sweden. English is my second language - corrections certainly may be needed and are always welcome. I mostly contribute on Swedish wikipedia, but sometimes I make minor edits on enwp. I am so impressed about Wikipedia which I often read, and I am happy to do minor corrections or improvements when possible.
It is so amazing how many skilful, talented, knowledgeable, creative and interesting wikipedians there are around. Below I just mention (in alphabetical order) some wikipedians on english wikipedia who I have in one or another way appreciated their efforts and contributions:
