According to the available biographical information, Kamara built an amateur career with seven national titles and a Senior Elite championship. In 2024, he won gold in the 71 kg category at the World Boxing Cup Finals in Sheffield, with a unanimous victory over Japan's Sewon Okazawa. At the 2025 World Boxing Championships in Liverpool, he won bronze in the 70 kg division. He won his first three bouts there by unanimous decision and lost in the semifinals by split decision to Kazakhstan's Torekhan Sabyrkhan. According to Wikipedia, Kamara formally switched to professional boxing on June 2, 2026. On August 17, 2026, Matchroom Boxing announced that he had joined Eddie Hearn's stable. The available sources describe his amateur weight as around 70 to 71 kilograms. Therefore, super welterweight is used as the expected direction, with the caveat that his official professional weight class had not yet been definitively confirmed. The Matchroom announcement named Tony Sims as part of his team. An earlier article reported that Kamara was still looking for the right coach, so this trainer information should be read with caution.
