In some ways, Gia Derza seemed destined for porn! It was something that came to her almost as second nature. "I always have been taking naked pictures of myself [ . . . ] It kind felt natural," Derza told Dave Naz in 2018. She'd also experimented sexually with escapades such as a foursome Originally from Ohio, Derza took an interest in porn as soon as she began to come into her own as a sexual person. With her interest piqued, she looked up "adult industry" online and found a place to post a profile for potential work in the field. Soon, she was contacted by a rep, and her career was under way! The excellence of her early work in porn earned her Best New Starlet nods at both AVN and XBIZ. As of 2021, Gia is represented by the prestigious Spielger Girl agency.

In 2021, she scored a notable cover role in Massive Curves 2, which spotlighted Derza's amazing booty. "Gia is captivating as she brings her inimitable curves and up-for-anything attitude with explosive results," said a studio rep at the time of the movie's release (as quoted by XBIZ).

Gia cites Abella Danger as one of her main role models in the industry. She regards herself to be submissive in terms of her own personal sexuality, and she counts horseback riding and yoga as some of her hobbies. (Though by her own admission, her hobbies have taken a back seat to her porn career in recent years!) Among Gia's preferred recording artists are Billie Eilish and The Weeknd.

While it's clear Gia is having the time of her life as a pornstar, she doesn't take a trivial approach to her job. As she told Dave Naz in 2018, "Take it seriously, like it's a job, not like it's fun, because it's a job."
