Self-introduction text

Hello, could you help me to review this self-introduction text ?
Thanks !

I learned studied electronics in at an engineering school in Vietnam. Thereafter, I went to France because advanced technology projects flourish there and the chocolate tastes better. I had an occasion the opportunity to work with experienced engineers in CEA for three years, and to write I wrote one patent and three academic articles in the wireless domain. My occupation is essentially Essentially, my job is to make applications based on the radio frequency available. Here, I would like to talk about 5G cellular mobile communications, contactless respiratory & cardiac monitoring, tags identifying & tracking, obstacle detection for autonomous cars, etc.

Note: The last sentence is a little hard for me to correct, because I don't know the context- when you say "Here, I would like to talk about...", where is here? Is this the opening for a speech? Awesome job, nearly perfect!
