Nadarajan Mudalier’s father was a Chetti Melaka and his mother was a Chinese Peranakan Nyonya from Melaka. He has six siblings, and they use the Baba Malay language at home to communicate with each other. However, they switch to the Chetti Malay language when they mingle among the Chetti community. He has practiced Chetti Melaka traditions throughout his life, even during the time he was away from his village for almost forty years. Upon his retirement in 2013, after thirty-five years of service with Petronas Bhd, he returned to Melaka and served the Chetti Melaka community as a trustee of Chitty Melaka Temple.
