MathLinks and Art of Problem Solving

In 2002, Vornicu founded an educational resources company known as MathLinks. In 2004, he merged the company with Art of Problem Solving, a company of which he was previously the webmaster. In 2010 he left the company though he is still involved in teaching for the online school.

International Mathematical Olympiad

Vornicu was a 2-time IMO participant, having won a Honorable Mention in 2001, and a Bronze Medal in 2002, but his involvement with the IMO did not stop here. He was Observer A with the Romanian delegation at the IMO 2003 in Japan, Observer B at the IMO 2004 in Greece, a Coordinator at the IMO 2005 in Mexico as well as the IMO 2006 in Slovenia, Observer B at the IMO 2007 in Vietnam and again a Coordinator for the IMO 2008 in Spain. He co-wrote one of the problems used in the IMO 2004 test. Currently, he is tutoring rising students for mathematical olympiads part-time.
