Vichaya graduated in architecture from King Mongkut's Institute of Technology Ladkrabang, and only had informal training in music.
Upon graduation, he joined the band La-Ong-Fong, and went on to pursue a career in music instead of architecture.
Vichaya went on to compose for Yuthlert Sippapak's 2003 film February, and co-wrote the score for Pen-ek Ratanaruang's Last Life in the Universe with Jettamon Malayota.
He composed several other works for Yuthlert and Pen-ek, and has since produced numerous further output, including works done with film studio GTH/GDH, of which The Teacher's Diary (2014), Heart Attack (2015), A Gift (2016), and Bad Genius (2017) all won the Suphannahong National Film Award for best original score.
In 2020, Vichaya composed the original soundtrack for the Thai mini-series, I Told Sunset About You.
