I came to US in Sep 2010 as F-1 Visa. My OPT period is Jan-Dec 2017, then switched to H1B. I am a full time employee in 2017. Do I count as a non-resident Alien for 2017?

My F-1 status is from Sep 2010 - Jan 2017. I graduated on Dec 2017 and started OPT from Jan-Dec 2017. In Dec 2017, my visa status changed to H1B. I am full-time employee since Mar 2017. Am I a nonresident alien or a resident alien?
