Upon graduation from ITI, Zachary collaborated with fellow graduates, Seng Soo Ming and Alberto Ruiz, in Unbound: Prometheus and The Monkey King, performed in Malaysia. He was also seen on stage in Boom! (2008) by the Singapore Repertory Theatre. In 2009, he was in Creative Lab, a presentation of eight solo works that were the responses by eight artists to Kuo Pao Kun’s The Spirits Play, the inaugural play of the Traditions & Editions Theatre Circus, a theatre collective established by ITI alumni. His solo went on to be presented in Kuala Lumpur. In the same year, he was also Assistant Director for The Quest for the 25th Virtue of Filial Piety by the Young People’s Performing Arts Ensemble. In 2010, he taught Theatre History in the Arts Business Management programme at Ngee Ann Polytechnic. A strong belief in actor training and a desire to expand his vision in theatre led Zachary to join ITI.
