The son of actress Jayachitra, Amresh appeared as an actor in his mother's productions Pudhiya Raagam (1991) and then in Naane Ennul Illai (2010), before working as a music composer in the late 2010s.
[1] Amresh first gained attention by composing for a four-language music album titled Jeevitham, which was released in 2008 and featured singers including S. P. Balasubrahmanyam, Karthik and Sujatha.
[2] Despite Jayachitra directing his debut through Naane Ennul Illai (2010), the film's failure made it difficult for Amresh to succeed as an actor.
[3] In 2011, it was announced that he would work on projects titled Kaliyuga Kadhalan and Machan Ava En Aalu Da, with the former being set in three different eras, but neither film was completed.
In a press meet in February 2017, Amresh Ganesh refuted the claims and provided evidence of Tinku and Robert continuously trying to scam him by gathering funds for the shelved project.
