Following his education at the University of Buenos Aires, he joined his father's company, the Bridas Corporation, founded by the Bulgheroni family in 1948.
The senior Bulgheroni died in 1985 and left a controlling stake in the firm to Alejandro and his younger brother Carlos.
[6] He was further involved during 1997 in negotiations between Bridas and the ruling Taliban faction in Afghanistan to build the Trans-Afghanistan Gas Pipeline from Turkmenistan to Pakistan.
[7] These negotiations were in competition with those undertaken by Unocal,[8] and although an agreement with Unocal-led corporation CentGas was reached, the deal was forfeited in January 1998 in favor of one with Bridas.
In 2006, Bulgheroni indicated interest in Bridas' involvement with the Trans-Afghanistan Pipeline project, which continued to be hampered by the ongoing chaos in the Central Asian nation.
