I have a strong technical background besides being an experienced writer. I have studied physics, biochemistry and electronics at the university level (University of California at Berkeley). Besides that, I know a good bit about mechanical engineering and construction.
I have not done a lot of work on this site. You can see examples of my work on the freelance site fiverr dot com, where you will also see that my customers are very satisfied with the quality of my work. However, the three projects I have done here got good reviews.
If you want very high quality, then I can do it for you.
regards,
David Troutman
