Chew started riding at the age of six. At the
Singapore 2010 Youth Olympic Games, she competed in show jumping and placed 17th. Chew was selected to be the first athlete to present the
Olympic oath at the
Youth Olympic Games. Chew later switched from show jumping to dressage, and became the most successful dressage rider for Singapore and the first Singaporean to compete at Grand Prix level, which is the highest in dressage. She competed as the first Singaporean dressage rider at the
2018 World Equestrian Games in
Tryon, where she ranked 56th. Following the withdrawal of New Zealand's rider from the
2020 Tokyo Olympic Games, a replacement rider was to be chosen from the Dressage Grand Prix held in
Le Mans, France. However, Chew was eliminated from the Games as her horse Tribiani was found to be bleeding from the mouth, caused by a stumble before the competition. ==Personal life==
