He trained seriously and, between approximately 2013 and 2016, toured with a professional ballet company as one of its youngest members, performing in productions that included The Nutcracker.

This dance foundation later supported his transition into acting. He began pursuing on-camera work around age 11 and made his professional debut in a short film in 2017.

Career Overview
