Navas and his brother Niyas Backer used to visit the filming location of
Venkalam, directed by
Bharathan — who was also from Wadakkanchery — and would perform skits at the artists' camp. Inspired by mimicry artists of the time such as
Jayaram and
Zainuddin, the brothers developed a keen interest in
mimicry and began performing on stage. Navas later joined
Kalabhavan, where he started doing professional mimicry shows. Eventually, he became independent and, together with his brother Niyas, founded Cochin Arts, under which they continued performing mimicry. Navas used to imitate his father's role in
Vatsalyam on stage. Sometime after his marriage, Navas wrote and directed the telefilm
Velicham, which also featured his wife Rehna. The couple also appeared together in the short film
Mandan Bench in 2015. The couple once again played leading roles in the 2025 film
Izha, which also marked Rehna's return to feature films. His final release before death was
Detective Ujjwalan (2025). ==Personal life and death==
