[2] After beginning his career as a child artist, he has worked on series including Thamarai, Lakshmi Kalyanam and Tamil Selvi.
In 2012, Ashwin finished working on a coming-of-age film titled Hi Da directed by Brindha Das, which had music composed by Vishal Chandrasekhar.
In early 2013, he completed a film titled Ayul Regai Neeyadi, where he worked alongside a new technical team.
Another film titled Kalaintha Kanavugal by director Kabilan, examining the relationship between parents and their children, also failed to be completed.
It later had a low-profile release across Tamil Nadu in February 2018, with a reviewer from Iflicks.com noting, "Ashwin Kumar plays the protagonist and has done a decent job".
