[5] Esteban studied at the Immaculate Conception Academy in Greenhills, San Juan, Metro Manila for high school, graduating in 2018.

[7] She later attended the University of Pennsylvania, where she graduated with an undergraduate degree in Applied Arts and Science major in Leadership and Communications, achieving summa cum laude honors in 2023.

However, due to the rink's closure and a lack of nearby alternatives, she dropped the sport and instead convinced her parents to allow her to enter a fencing club at Xavier School.

[10] Esteban competed for the Ateneo Blue Eagles fencing team at the University Athletic Association of the Philippines (UAAP).

[11] After dominating her matches with three gold medals, Esteban led the Ateneo Women's Fencing team to win the UAAP Season 81 overall championships breaking the 11-year reign of the University of the East.

[21] In April 2024, the Philippine Fencing Association released a statement, reasoning that it was obliged to send only Samantha Catantan to the qualifiers out of merit (results since 2017) and noted the waiver it had given to Esteban for her sporting nationality change.

[22] In response, Esteban insisted that she was unjustly removed from the national team but expressed sadness that her former teammate's name was dragged into the controversy.

The move was approved by the Philippine Fencing Association, which waived the three-year waiting period requirement, allowing her to compete for the African nation immediately.

[23] Esteban's first podium finish for Ivory Coast was at the 2023 African Fencing Championships in Cairo, Egypt, where she clinched a bronze medal in foil.

[9] Prior to her sporting nationality change, she had already been holding clinics for fencers in Cote d’Ivoire,[4] and her family has long-standing ties with the country.
