He was educated at Nalanda College Colombo. He was recognised as a good off spinner in Sri Lankan domestic cricket before their elevation to Test status, and played in Sri Lanka's inaugural Test against England at Colombo in 1981/82. However, Kaluperuma bowled 21 wicketless overs, followed by six wicketless overs in the next Test. It was evident that the captain Duleep Mendis had little faith in him, and he never returned to international cricket. He joined an unofficial Sri Lankan tour of South Africa in 1982/83, which led to a ban from international cricket.
In 2003, he joined the board of national selectors in Sri Lanka, and two years later he was made chairman of the board.
