John Peter worked as a bureaucrat before first working as a musician on Prathi Gnayiru 9.30 to 10.00 (2006), which had a delayed release. He subsequently went on to work closely with Harikumar who gave him the chance to compose the songs for Madurai Sambavam (2009) and Bodinayakanur Ganesan (2011). Similarly, Vadivudaiyan gave him the chance tp work on two films, Kanniyum Kaalaiyum Sema Kadhal and Sowkarpettai (2015), which became John Peter's most high profile project. In 2015, he also worked on the Vijay Vasanth-starrer Vanna Jigina, produced by N. Linguswamy.
