I'm a native US English speaking/writing, college educated, American professional. I have writing samples available I will email upon request. I do a good deal of term paper/thesis writing, so I cannot post samples publicly online.
Professionally, I'm currently a writer with a British-based professional writing service where I specialize in academic writing. My areas of focus are technology/computer science, philosophy, sociology, history and chemistry - though I've written graduate level business papers as well. If interested, or you have additional questions, please feel free to contact me.
Sincerely,
Mark Davis
