Karanga began his professional career with Santa Cruz, but failed to cement a first team place and spent loan spells with Bragantino and Belo Jardim before joining Trindade on a permanent basis.

On 29 April he scored a goal in the Eternal derby of Bulgarian football, netting the third in CSKA's 3–0 win over Levski Sofia.

[1] Karanga began the 2017–18 season with a goal in the first league game against Slavia Sofia on 15 July, which ended in a 1–1 draw.

He continued his fine performances during the first months of 2018, but sustained an injury in the second leg of a Bulgarian Cup match against Levski Sofia on 25 April (after a rough tackle), which sidelined him until the end of the season and was a factor in him finishing in second place for the top goalscorer award in the league.

[13] During his second stay with the "redmen", he managed to find the net on 5 occasions, becoming the foreign player with the most goals in the league for the team,[14][15] but his stint was marked by disciplinary issues, resulting in two red cards, for the latter of which, received in a heated match against Ludogorets Razgrad, he was handed a six-match ban.
