Born in Mountain Ash, Rhondda Cynon Taf, O'Sullivan progressed through the Academy at Cardiff City to sign his first professional contract in 2012. His made his professional debut when he came on as a substitute for Stephen McPhail 19 minutes into a 2–1 League Cup defeat to Northampton Town at Sixfields Stadium on 14 August 2012.

O'Sullivan joined League One side Port Vale on a one-month loan on 2 February 2015; manager Rob Page signed O'Sullivan to replace injured creative midfielder Louis Dodds, having been familiar with him from his time as a coach with the Welsh youth teams. He returned to Cardiff on 2 March after only one substitute appearance at Vale Park. Ten days later he was re-signed by Page on another one-month loan, after the departure of Chris Lines created a midfield vacancy in Vale's first team picture.

On 5 October 2015, O'Sullivan was named as Welsh Young Player of the Year by the Football Association of Wales. Eight days later he joined Newport County on an initial one-month loan, subsequently extended until 7 January 2016. He made his debut on 17 October in 1–0 home defeat by Portsmouth, and on 24 October, he scored his first professional goal in Newport's 4–1 win at Bristol Rovers. In total he made 13 appearances for the club during the loan spell, which was not extended despite Cardiff manager Russell Slade being encouraged by O'Sullivan's progress.
