A well-known name in his hometown, Sweden Fernandes has been an active part of the local leagues in Goa, turning up for the youth teams at Sporting Clube and Dempo SC. His quality was noticed by FC Goa, who picked him up for their youth team in 2017. Ever since, he has been a regular in the reserve and youth sides, playing local and national competitions like Goa Pro League, Durand Cup and the Second Division League. The 20-year-old was roped in by Hyderabad FC this year ahead of the 2020-21 Indian Super League campaign and has since spent a couple of loan stints with NEROCA FC, where he helped them to a strong season but failed to break into the first team at HFC before his contract came to an end in 2023.
