Hi, my name is Ernesto.
I am a mathematician; I was a university professor until 2014.
I have more than 9 years of experience in content development and questions/solutions writing for sciences, engineering, technology and mathematics, including SAT, GMAT, GRE, IIT-JEE (main and advanced), contests and olympiads.
If my skills and experience meet your requirements, I would like to carry out an interview.
Kind regards,
Ernesto.
