Early life

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]

Career

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] Tjen reached the top 100 on 6 October 2025 and became the sixth Indonesian to reach the milestone.^[20]
