Ruta began karting in 2022, competing until 2024. During his short karting career, Ruta most notably finished second in the 2024 Rok Cup Poland's Senior Rok standings, and also participated in the 2023 Rok Cup Superfinal, also in Senior Rok. In early 2025, Ruta made his single-seater debut by joining
Cram Motorsport to race in the
Formula Winter Series. After scoring his first points in race one at
Aragón by finishing tenth, Ruta switched to
Van Amersfoort Racing for the season finale, where he scored points again by finishing 11th in race one, en route to a 21st-place points finish. Despite being set to race in
Italian F4 for Cram, Ruta elected to continue with VAR to race in the series, as he started off the season with seventh- and eighth-place finishes in races three and four in round two at
Vallelunga, as well as a rookie podium in the former. Ruta then scored two points finishes between the
Mugello and
Barcelona rounds, before ending the season with a pair of ninth-place finishes at
Misano to end the year 23rd in the overall standings. During 2025, Ruta also raced with the team in the
E4 Championship, in which he scored four rookie podiums between the
Le Castellet and
Mugello rounds, including a best overall result of seventh in the latter's race one to take 13th in points. Remaining with Van Amersfoort Racing for 2026, Ruta raced with them for a triple campaign in the
Formula Winter Series,
Italian F4 and
E4 Championships. In the Winter Series, Ruta began the year by scoring points four times across the
Estoril and
Algarve rounds, before finishing on the podium in all three races at
Valencia, which included his first-ever career win in race two. Ruta then finished tenth in race one in the following round at
Aragón, before skipping the remaining two races and the season-ending
Barcelona round after injuring his hand in said race. ==Karting record==
