Born in Cabra del Camp, Tarragona, Catalonia, Calavera finished his youth formation with Gimnàstic de Tarragona, and was called up to the first team by manager Santi Castillejo for the pre-season in 2013.
He made his senior debut on 25 August of that year, starting in a 1–2 home defeat against Lleida Esportiu for the Segunda División B championship. Two days later, Calavera renewed his link with Nàstic, signing until 2016, and was definitely promoted to the main squad, as a replacement to Sporting de Gijón B-bound Alberto Benito. However, he spent the whole campaign mainly as a backup to Juanjo, as his side missed out promotion in the play-offs.
On 19 January 2015, after being again second-choice (now to another new signing, Gerard Valentín), Calavera was loaned to UE Olot also in the third level, until June.
On 9 September he made his professional debut, starting in a 2–2 home draw against Girona Football Club for the season"s Copa del Rey (5–4 success on penalties). On 27 September 2015 Calavera made his Segunda División debut, coming on as a half-time substitute for Xisco Campos in a 0–0 away draw against Real Valladolid.
On 17 October he scored his first goal in the category, netting the first in a 2–1 home success over Bilbao Athletic.
