[7] [8]
Tjen was selected to represent Indonesia at the 2022 Asian Games and won the bronze medal in doubles while partnered with Aldila Sutjiadi. [9] [10]

[12] [13] [14] Tjen lost in the second round to Emma Raducanu in straight sets. [15]
In September 2025, on her WTA 250 debut at the São Paulo Open, Tjen became the first Indonesian woman to reach a WTA quarterfinal since Angelique Widjaja at the 2004 Wismilak International.
