Although born in Banat, Alexa was considered disposable while at UM Timișoara in 1998, and he moved to Rocar București where he helped his side reach the 2000–01 Romanian Cup final.

After several years with short spells at FC Timișoara and Universitatea Craiova, Alexa got his big chance as Dinamo București decided to transfer him.

In the summer of the same year, Politehnica boss Marian Iancu decided to bring Alexa – by then, a real "persona non-grata" in Timișoara, due to his pledge of loyalty to Dinamo – back to the city where he started his career, together with teammate Ştefan Grigorie.
