Currently I'm working as electrical engineer in PET plastic factory and I've decided to come here and apply and provide my knowledge for everyone who needs it. Here is a small summary of my experience. Microsoft programs - during the years of my studies there was a lot of use of these programs to write an essay's, calculate data, making reports, presenting it to others. I'm well aware of microsoft programs such as word, power point and excel. also I took extra online course for excel VBA programing for my own interest for this reason I'm able to automate any repetitive job that you have in excel. Electrical - I've finished Maritime academy in a roll of "Marine Electrical and Electronic Engineering". Today I have more than 5 years of experience as electrical engineer. 3 years as a world wide ships electrician and 2 years as electrical engineer in shore industry. This also includes my experience with autocad, mainly with electrical drawings. menos
