Tjen was born in Jakarta, Indonesia. [6] She was persuaded to take up tennis by Priska Madelyn Nugroho, a friend and one of the top Indonesian junior players at the time. [7] The high costs involved with turning professional meant that Tjen and her parents decided to develop her skills through college tennis first; Tjen played at the University of Oregon, then transferred to Pepperdine University in 2021, graduating in 2024 with a degree in sociology. [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]
In August 2025, Tjen qualified for her first Grand Slam main draw with a straight sets win over third qualifying seed Aoi Ito at the 2025 US Open. She became the first Indonesian player in a major since Angelique Widjaja at the 2004 US Open. [11] In the first round, she defeated 24th seed Veronika Kudermetova in three sets, becoming the first Indonesian woman to win a Grand Slam match since Widjaja at the 2003 Wimbledon Championships. [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. [16] After defeating third-seed Alexandra Eala in the quarterfinals and sixth-seed Francesca Jones in the semifinals, [17] Tjen became the first Indonesian player to reach a WTA final since Widjaja in 2002. [18] She lost the final to Tiantsoa Rakotomanga Rajaonah. [19]
In October 2025, partnering Aldila Sutjiadi, she won her first WTA 125 doubles title at the Suzhou Open, defeating Katarzyna Kawa and Makoto Ninomiya in the final. [20] Tjen reached the top 100 on 6 October 2025 and became the sixth Indonesian to reach the milestone. [21] She won her maiden WTA 125 singles title at the Jinan Open, overcoming Anna Bondár in the final. [22] Teaming with Katarzyna Piter, Tjen won her first WTA 250 doubles title at the Guangzhou Open, defeating Eudice Chong and Liang En-shuo in the final which went to a deciding champions tiebreak.
