Navin began to learn the flute aged five and continued to learn both Carnatic and Western interpretations of the instrument throughout his childhood. In 2005, he received an opportunity to work on the "Luka Chupi" song in Rang De Basanti (2006) as a flute player in A. R. Rahman's music, and the opportunity marked his first film performance. Navin worked as a flute player for more composers including Harris Jayaraj and G. V. Prakash Kumar, before working as a music composer on R. S. Prasanna's Kalyana Samayal Saadham (2013). For the film, he preferred to be credited under the stagename of Arrora however he later reverted to his real name. He later also worked on the Mohanlal-starrer, Peruchazhi (2014), his first release in Malayalam.
He has since worked on the compositions of Tamil films including Oru Naal Iravil (2015) and Vil Ambu (2016), notably picking three music composers to record songs for his work in the latter. His biggest venture as a film composer till date is the 2014 Malayalam film Peruchazhi directed by Arun Vaidyanathan starring Mohanlal.
