After successfully representing hometown's UD Las Palmas – having started out as an attacking midfielder at his first club CD Arguineguín[1][2]– he was bought in July 2007 by Deportivo de La Coruña for €600.000, signing a five-year contract.

[3] He only appeared once for the Galicians in his first year, a 0–2 home loss against Recreativo de Huelva[4] and, in January 2008, was loaned to Xerez CD in the Segunda División.

[5] The loan was renewed for the entire the 2008–09 season,[6] and Aythami was an instrumental defensive element for the Andalusians, which achieved a first-ever La Liga promotion.

[11][12] The free agent re-joined Las Palmas in the summer of 2013 after agreeing to a four-year deal,[13] contributing three goals[14][15][16] from 37 appearances in 2014–15 (play-offs included) as the latter returned to the top tier after a 13-year absence.

[20] Aythami signed a one-year deal with Primera División RFEF side Gimnàstic de Tarragona on 22 July 2021, having arrived for free.
