Stephen Devassy is a man who built himself upon his dreams. He did his schooling at 7th day Adventist high school, Ottapaalam from where he started walking into the world of music. He got his first ever keyboard of his own, as a gift from his Dad PK Devassy, from when and where he started to pave his way forth as a musician. Stephen had started to learn to play keyboard since when he was in the 5th standard. He used to perform in churches even during his small age which finally gave him the confidence to present himself in a show before the public, and that too when he was in the 8th standard. As he made his way to NSS College, Ottapaalam to do his pre-degree, he had made up his mind not to let go of music ever in his entire life. This gave him the motivation to develop himself and gave him the opportunity to do his first tour abroad while he was in the first year of his pre-degree, with the legendary singer Padmashree Hariharan. The passion in him grew to know no limits with what he achieved his degree and a record by completing his 8th grade piano at the age of 16 from Trinity College, London. His keyboard tutor was Leslie Peter and his Piano teacher was Fr.Thomas Chakalamattath, Chetana Academy at Thrissur.
Stephen Devassy never found it hard to be active in the NCC too, along with his experiments with music. He still finds his selection of being one among the only 3 NCC cadets selected from Kerala to represent the state, for the Republic day parade at Delhi during the year 1998, as one of the greatest recognitions he has got.
A R Rahman's music has influenced Stephen to explore more about the technical aspects of Sound Engineering and Music Production. He started recreating the tones used in ARR songs. This interest developed at a very fast rate and Stephen started doing keyboard programming for many leading music directors in Malayalam. Passion for music took him to next level, when he shifted to Chennai during 2003. His music programming skills gave Stephen an own identity in the Tamil industry and soon he became one of the busiest keyboard programmers in the industry. His music production style took him to the Bollywood scene, where he worked as the programmer for music directors like Shankar-Ehsaan-Loy, Anu Malik etc.
