She made her first appearance with Soul Sisterz at the 2009 Gyeongpo Dance Festival as the group's youngest member, performing
waacking. In 2011, Jeong formed the dance crew Purplow and was put in charge of artist choreography at
AOMG. During her time with Purplow, she became friends with rapper
Jay Park, with Jeong participating in a choreography video for Park's "Me Like Yuh". She later departed Purplow and formed the hip‑hop-focused dance crew HolyBang in September 2017. She continued to perform alongside Park, appearing at the 2018 Grand Mint Festival and the 2019
Waterbomb festival. Jeong and the other members of HolyBang competed on the dance competition series
Street Woman Fighter in August 2021, joining seven other crews. HolyBang won the competition in October 2021, defeating runner‑up Hook and fellow finalists Lachica and Coca N'Butter; the crew received ₩50 million, a trophy, and an opportunity to sign an advertising contract with a global beer brand, in which they signed with
Budweiser. After her win, Park asked that she not join his backing dance crew, expressing a desire for her to pursue an independent career; they did not perform together onstage until 2024, when they both appeared at the Waterbomb festival. In May 2022, Jeong signed with
More Vision, a label founded by Jay Park. Jeong was the first artist signed to More Vision and released the songs "Look" and "Honey Drop", collaborating with producers Blase and Bronze and featuring artist Lil Cherry. Jeong formed a new dance crew, Bumsup, to compete in the third season of the
Street Woman Fighter series,
World of Street Woman Fighter in 2025, alongside fellow alumni Aiki and
Leejung Lee. Their performance amassed nearly 16 million views, described by
The Korea Times as the most ever across the
Street Woman Fighter franchise. During filming, Jeong and Aiki drew criticism for making inappropriate remarks towards another team, with both issuing apologies for the remarks. The team was eliminated in the eighth episode, finishing behind Motiv, AG Squad, and Osaka Ojo Gang. == Other ventures ==
