At the 2012 Summer Olympics he finished 33rd overall in the heats in the Men's 400 metre individual medley and failed to reach the final. Quah was Singapore's flag bearer for the 2013 Asian Youth Games. He won three individual gold medals and a silver medal at the 200 m backstroke, 200 m butterfly, 200 m individual medley and 200 m freestyle events respectively.

At the 2016 Rio Olympics, Quah achieved a personal best time in 200 meters butterfly in the heats. He was the first male Singaporean to qualify for a semifinal berth at an Olympics swim competition. He is one of two Singaporean male swimmers to have qualified for two semi-final berths at the Olympics.

Due to his potential at winning Olympic medals for Singapore, Quah was granted National Service (NS) deferment until the 2020 Olympic Games. Due to the COVID-19 pandemic, the 2020 Olympic Games was delayed to 2021 and his NS deferment was extended to 2021.

In the 2020 Olympic Games, Quah competed in the 100m butterfly, the 200m butterfly and the 100m backstroke. He failed to clock personal best times and did not make it to the semi-finals for the three events.

Quah returned to Singapore after a 5-year programme at the University of California, Berkeley, and is currently serving his National Service. However, Quah noted that he was "at a crossroads of some big life decisions" and desires to continue swimming.
