I have two degrees and have spent a lot of my time working in offices, hospitals, and universities. I seem to know almost anything to do with computers, the Internet, science and engineering. I have even written two scientific papers which have been published and presented at international conferences. In my spare time I am great sound engineer and play in a band. My native language is English and my French is pretty good.
I am not a wikipedia expert because I don't have the time for that but, I use it almost every day for both work and play. When I notice mistakes or something missing I will try to add something or fix it. Some topics interest me a great deal so I watch those pages and when I have time I will fix them and improve them over a long period of time.
