Daja was born in the Albanian capital Tirana, which is where he began playing football at the age of 8 with local amateur youth side Pallati i Pionerëve under the guidance of coach Hyqmet Kuka.
[3] Just four days later he came on in the 54th minute away against Vllaznia Shkodër and scored his first ever senior goal in the closing stages of the game to make it 3–0 for the team.
[4] For the 2008–09 season Daja became first team player but failed to establish himself in the starting line up due to his age and lack of experience.
[6] On 8 July 2014, Daja joined Partizani Tirana on a free transfer, signing an initial one-year contract with an option of a further one.
[9] Daja undertook a part-time degree at the Academy of Physical and Sports Education Vojo Kushi, commonly known in Albanian as the Universiteti i Sporteve Të Tiranës.
