Growing up in Budapest with her mother and older brother, Shine was a good student and popular amongst her peers. By her mid-teens she began to discover her sexuality, having her first sexual experience (oral sex) with a boy in a public park at 15. A week later she experienced intercourse with him. Her first sexual experience with a woman happened when Sandra was celebrating her 18th birthday. She and her boyfriend met a girl at a nightclub and brought her back to her place for a threesome.

Shine worked as a fashion model before she was an adult model, starting at 15, but finding the pay was not enough to suit her, started posing solo for nude photoshoots when she was 18. A couple of years later she was doing lesbian shoots as well. Shine fully entered the adult industry in 2001 under the alias of "Judith Devine". As Judith, Shine became Penthouse Pet of the Month for February 2001, while still in college as a business major. She also starred in the 2002 adult movie, Reality 6 - Dangerous Games, and was again made Penthouse Pet of the Month for August 2003.

Sandra Shine has frequently done lesbian scenes with Zsanett Égerházi, Sophie Moone, Jordan Maze, and Anetta Keys. Her two available heterosexual works are an early softcore male-female-male-female photo shooting where she also performs fellatio on one of the actors as an "extra" and a video named Interview with a Sex Maniac, originally shot for television where she has sex with her real-life fiancé (then boyfriend).

Sandra Shine is currently engaged to her long-time boyfriend.
