During his scholarship, Duffy spent a number of periods on work experience with local non-league sides. In November 2004, he linked up with Grantham Town, celebrating his 18th birthday by keeping a clean sheet on his Grantham debut. At the turn of the year he joined Bourne Town.
At the beginning of the 2005–06 season, he spent an eventful spell with Buxton. He produced a Man of the Match display, including a penalty save, against Newcastle Town in the FA Cup only for Newcastle to protest about his eligibility; the protest was unsuccessful. In the league game against Maltby Main he was beaten by a long punt from his opposite goalkeeper. In December 2005, he assisted Lincoln Moorlands. In January 2006, he joined Stamford. He stayed at Stamford before Lincoln recalled him, to enable him to link up with Cambridge United. He played twice for the Us, suffering an unfortunate debut when he palmed the ball into his own net against Morecambe. He was, however offered support by the then Cambridge boss Rob Newman. He returned to Stamford, helping them to promotion to the Southern League Premier Division with a play-off victory against Wivenhoe Town.
In the summer of 2006, Duffy accepted a one-year professional contract with Lincoln City. His first season saw him spend time on loan at Worksop Town where a broken leg ended his season. He accepted a further one-year contract and on 12 April 2008 made his professional debut, replacing the injured Alan Marriott in the 2–1 victory against Chester City.
On 19 April 2008, he made his full home debut for Lincoln in a 3–1 victory over Brentford. On 5 May 2009, he was released by Lincoln City.
On 8 July 2009, Duffy signed for Corby Town, but he was released a few weeks later. He moved on to join Gainsborough Trinity on non-contract terms as cover for the injured Phil Barnes, appearing in the 2–2 friendly home draw with Boston United on 1 August 2009, but was unable to play for the club in the Conference North as The FA ruled that Corby Town still held his registration.
In September, he linked up with Hyde United, marking his debut by being sent off for conceding two penalties, in the 17th and 55th minute, in a 5–1 home defeat to Alfreton Town on 5 September 2009. He made a further appearance in Hyde's 1–1 home draw with Gloucester City two days later before departing the club to join Grantham Town. In February 2010, he moved to Lincoln Moorlands Railway. In September 2010, Duffy joined Sleaford Town on loan, debuting in the 3–0 United Counties Football League Premier Division home defeat by Irchester United on 18 September 2010. He joined Staveley Miners Welfare for the 2011–12 season, debuting in the club's 1–0 Northern Counties East League victory at Brighouse Town on 6 August 2011.
Having left the professional game, Duffy enrolled in a course studying education studies and sport at Bishop Grosseteste College. Duffy has now gone on to become a Physical Education teacher at the prestigious Hills Road Sixth Form College in Cambridge.
