Ercan Osmani was born on August 4, 1998, and holds both Albanian and Turkish citizenship. He is listed as the "TUR" player for the Turkish National Basketball Team in official international records.

Ercan Osmani played his first season in the EuroLeague, Europe's premier club organization, in the 2023-24 season with Anadolu Efes. He joined the EuroLeague A Team this season, where he was a regular on the roster and played in the organization's highest-profile matches.

He has played all of his professional club matches in Türkiye. He began his career with the Bandırma youth academy and has since played for Turkish teams such as Bilançonya Kırmızı, Bandırma BK, Beşiktaş, Darüşşafaka, and currently Anadolu Efes; his only international representation is with the Anadolu Efes squad in the EuroLeague.

Osmani's journey with the Turkish National Team began at the 2022 FIBA EuroBasket, where he then played for the national team in the 2023 FIBA World Cup European Qualifiers and the Olympic Qualifying Tournament held that same year. This continued into the 2025 EuroBasket Qualifiers, where he earned a place on the team roster, both playing time and contributing as required by his position.

Ercan Osmani primarily plays the roles of power forward and center. His height of 206 cm and his understanding of perimeter defense give him the flexibility to be used in two different big man roles, both offensively and defensively.

He was part of Anadolu Efes's Turkish Cup squad for the 2023-24 season. While TBF data includes match records from cup competitions for this season, no official championships are listed for his team during that period.

He has yet to win a medal in any international tournaments with the senior national team; he has participated in the 2022 EuroBasket, the 2023 World Cup European Qualifiers, the 2023 Olympic Qualifiers, and the 2025 EuroBasket Qualifiers. Despite his performance in European and Olympic qualifying competitions, he has yet to achieve a podium finish.
