Sebastian Alejandro Castillo Perez

Castillo's first goal for Deportivo La Guaira came against Zamora FC.

He had made that senior debut for Zamora on 10 July 2022, against Deportivo Lara, and left for La Guaira on 1 January 2023. He debuted against Monagas on 5 February and finished the year with 24 league appearances and five goals. The following season was leaner — 21 matches, one goal — and 2025 became his most productive year in Venezuela, with 31 league appearances and six goals.

On 2 January 2026 Castillo moved to Ukraine, joining Metalist 1925 Kharkiv on loan until 31 December 2026. The fee was not disclosed. In May 2026 the club changed its name to FC Kharkiv, keeping the squad intact.

His Ukrainian record so far runs to 15 matches: ten in the Premier League in 2025/26, three more in 2026/27, and two in the Ukrainian Cup. He has supplied two league assists and scored once in the Cup, in the current season. No individual awards or club records have been recorded during his time in Kharkiv.

Internationally, Castillo has played for Venezuela at under-20 level, including at the South American U-20 Championship and in friendlies, without scoring. He has not appeared for the senior national side.
