Born in Arcozelo, Vila Nova de Gaia, Guedes joined Sporting Clube de Portugal's youth system in 2005, aged 11, and went on to score 53 goals for its various teams. On 16 December 2012, still a junior, he made his senior debuts with the B-side, coming on as a substitute for Bruma in the last minute of a 2–1 away win against C.D. Tondela for the second division championship.
On 29 January 2014, Guedes was loaned to Spanish club CF Reus Deportiu until June, alongside Sporting teammate Tobias Figueiredo. He failed to find the net during his one-and-a-half-season stint in Catalonia, and in the summer of 2015 agreed to a two-year deal at C.D. Aves in his country's second level.
Guedes scored 13 goals in each of his first two seasons in Aves, helping to Primeira Liga promotion at the end of 2016–17 and subsequently renewing his contract. He made his debut in the competition on 6 August 2017, playing the full 90 minutes in a 0–2 home loss to former club Sporting.
