Rahul Sharma had already started acting and modeling when he was in Class 9 and 10 but familial responsibilities made him opt for further studies instead of pursuing acting. After completing a BMM degree, he went to Kota and began preparing to give the medical entrance exam. Luckily, around the same time, he received an opportunity in the line he wanted.

Rahul consequently made appearances in several music videos as well as TV commercials, including a popular Tata Sky advertisement with Suniel Shetty. After training in an acting academy, Rahul started going for auditions but faced several rejections because he didn`t fit the stereotypical appearance of a male hero. Nevertheless, he persevered and bagged the lead role in X Ray: The Inner Image, a 2019 film where he shares the silver screen with actress Yaashi Kapoor.
