Born in
Montevideo, Kuki moved to Spain at early age and started his career with
Albacete Balompié's youth setup. On 30 May 2012, aged only 14, he was signed by
Málaga CF. Kuki made his senior debut with
the reserves on 31 August 2014, starting in a 0–0 home draw against
Atlético Mancha Real in the
Tercera División. The following March, he was linked to potential moves to
Premier League sides
Liverpool,
Chelsea and
Manchester City. Kuki scored his first senior goal on 30 August 2015, in a 3–3 home draw against
CD El Ejido 2012. The following January, he was targeted by
FC Barcelona. On 24 June 2017, Kuki scored a brace in a 4–2 home win against
AD Unión Adarve, but his side narrowly missed out promotion in
the play-offs. On 8 August, he was loaned to
Segunda División B side
FC Cartagena, for one year. On 30 August 2018, Kuki moved to another
reserve team,
Real Valladolid B in the third division. He made his
first-team debut on 31 October, starting in a 2–1 away defeat of
RCD Mallorca, in
the season's
Copa del Rey. Zalazar made his
La Liga debut on 19 January 2021, coming on as a late
substitute for
Roque Mesa in a 2–2 home draw against
Elche CF. On 27 August, after the Valladolid's
relegation, he moved to
Segunda División side
SD Ponferradina. On 31 August 2022, Zalazar terminated his contract with
Ponfe, and signed a two-year deal with
Primera Federación side
Deportivo de La Coruña just hours later. Roughly one year later, he agreed to a one-year contract with
Córdoba CF. On 30 June 2024, after helping the
Blanquiverdes in their
promotion to the second division, Zalazar signed a new one-year deal with the club. The following 3 February, however, he terminated his link and signed a one-and-a-half-year contract with
