He is known for the melodious composition of chartbuster Kannukkul Nooru Nilava... from the Bharathiraja directed film Vedham Pudhithu released in the year 1987.
However, since the project was dropped, producer Kovaithambi hired Devendran to debut in film with Mannukkul Vairam.
The film's song "Pongiyathe Kadhal" was based on the school composition that Sundarrajan appreciated.
Devendran later composed the music for Bharathiraja's Vedham Pudhithu, where the song "Kannukkul Nooru Nilava" attained popularity.
