Mahmudul Hasan Joy is a technically sound top-order batter from Bangladesh known for his solid temperament and classical strokeplay. He made his First-class debut in 2019 for Chittagong Division and announced himself with a fine half-century. His List A debut followed in the same year, representing Prime Bank Cricket Club. In the T20 format, he made his debut during the 2021 Bangabandhu T20 Cup, gradually adapting his game to the shorter version as well.

Domestically, Joy rose through the ranks with consistent performances, particularly in longer formats where his patient approach and sound technique have stood out. He was a part of the Bangladesh U-19 team that won the 2020 ICC Under-19 World Cup and played a pivotal role in their historic win, scoring a crucial fifty in the semifinal against New Zealand. That performance highlighted his ability to handle pressure in big moments and earned him a fast-track entry into senior domestic cricket. Joy made his Test debut in 2021 against Pakistan, but had to wait for a couple of more years to play his first white-ball game for Bangladesh, and he did that in the 2023 Asian Games where they won the Bronze Medal.

Internationally, Mahmudul Hasan Joy made headlines when he became the first Bangladeshi batter to score a Test century against South Africa, a gritty 137 in Durban in early 2022. While his opportunities at the international level have been somewhat limited, he remains in the mix, especially in Tests where Bangladesh continue to groom him as a key figure for the future.
