Born in Menziken, Kraljevic represented Switzerland in a 2009 Fed Cup tie against Australia in Mildura, as a 15 year old.

Kraljevic, a right-handed player, won her only ITF title in the doubles at à  ibenik in 2011, which was her final year on tour. She gave up on tennis to complete her schooling and went on study medicine.
