Born in St Asaph and brought up in nearby Dyserth, Maxwell began his career as a trainee with Liverpool.
He became a regular in the reserve team, keeping Steven Gerrard out of the squad on occasion, and signed a professional contract with the club by the time he was 19.
Maxwell returned to Cardiff for the start of the 2003–04 season, but only made two more appearances before being granted a free transfer to Swansea City in March 2004.
[1] It was at Bangor that Maxwell finally managed to hold down a first team place, making 31 appearances and scoring 4 goals, but he was yet again sold on at the end of the season and moved to Caernarfon Town in July 2006.
After an inconsistent spell at Caernarfon (his final season yielded only 13 starts and 1 goal), Maxwell went on trial with Port Talbot Town in the summer of 2008, but failed to earn a contract.
[5] In 2020, Maxwell was arrested in the National Crime Agency's Operation Venetic after they broke the encrypted Encrochat messaging service.
