KeG Seoul and Griffin (2017–2019) Doran joined the Seoul national team in 2017 and the following year, he competed in the KeG Championship and KeSPA Cup. In the opening round of the knockout stage of the KeSPA Cup, Seoul defeated HLE but they were eliminated by DWG. After graduating from high school, Doran joined
Griffin's youth training program. Griffin headed into the 2019 LCK Summer Split with a new top laner, Choi "Doran" Hyeon-joon, and finished the regular season in first place with a 13–5 record. This placement secured the team a bye to the finals and a spot in the
2019 World Championship, as a series victory would give them a direct qualification as the LCK's first seed, while a series loss would still earn them the most championship points and qualification as the LCK's second seed. Griffin lost to SKT in the finals, with Griffin only managing to take a single game off SKT.
DragonX (2020) In late 2019, Doran transferred to
DragonX. His team would lose to

T1 in the final 3–0 to qualify as the first seed for the
2022 World Championship. They also won the 2023 Spring and Summer Splits.
Hanwha Life Esports (2024) Doran played for
Hanwha Life Esports in 2024. His team won the Summer Split by defeating his former team Gen.G by five games.
