An ethnic Sindhi, Girish was signed for the Bollywood romance filmRamaiya Vastavaiya, directed by Prabhu Deva and produced by his father Kumar S. Taurani, who is the managing director of Tips Industries Limited. In this film he played the role of Ram, a foreigner who was very rich, his role showed how agile and open his character truly is. Prabhu Deva trained Girish for three and a half years before the filming. To launch Girish, Prabhu Deva was signed close to three years back. Prabhu Deva decided to have an audition for him. As a result, Girish had to perform on a few scenes and also a dance number. Prabhu loved his performance, and thought that Girish had an X factor, requiring only more spontaneity and minor improvements. He talked with his parents about giving him dancing training and later, he selected some 25 songs and gave them to Girish so that he could practice them. He also appointed a few choreographers who worked on a daily basis with Girish in order to prepare him well for all formats of dances that were required for films. Girish was also overweight and had to take up to bodybuilding during his three years' training sessions. A trainer from South Africa was brought on board to check Girish's fitness. It was one of his greatest achievements that he developed six pack abs within 3 weeks. Regarding his looks in Ramaiya Vastavaiya, Prabhu Deva was reported to be happy and satisfied. For the first appearance of Girish in Ramaiya Vastavaiya, director Prabhu Deva and cinematographer Kiran Deohans planned a special introductory scene which is completely new to Bollywood. Marking his first ever appearance on the big screen, Girish made a dare devilish surfing sequence that hadn't been attempted in films so far. International surfing expert Christopher Bryan from Hawaii, United States was given the charge of the underwater sequences with Girish, which were shot in Australia. Girish was trained at Mantra Surf Club near for this. Taran Adarsh of Bollywood Hungama commented on his performance: "Girish being a first-timer, there are some rough edges, but the fact is, he's photogenic and goes through the rigmarole with confidence." Sarit Ray of Hindustan Times gave a less favourable review of his portrayal, saying "His dancing, unfortunately is only slightly less stiff than his acting." The film earned little praise from critics and underperformed at the box office. In 2016, Girish appeared in Loveshhuda, a romantic comedy opposite Navneet Kaur Dhillon. He played the role of Gaurav, a man who drinks and then wakes up with a girl whom he doesn't know. The film was released on 19 February 2016. The film earned little praise from critics and bombed at the box office. He next starred in Collateral Damage, a short film on an archaic practice that exists in villages. The film was released on 29 November 2018 and was screened at many film festivals. Girish has two upcoming releases in 2019, one being Adhoora opposite Chetna Pande.
