He made his directorial debut with Elevator (2008), an indie production adapting Gabriel Pintilei's stage play of the same title.

Dorobanţu's first Elevator has been notable due to the claim that it was made with a fund of 300 euro.

Elevator was followed by Bucharestless, which was a cinéma verité or a documentary about the Romanian capital.

The 2011 film had an outside-the-box cinematic perspective, with a sequential narrative approach, and no dialogues.

The post-apocalyptic film called Omega Rose followed Bucharestless, although it was only completed in 2018.
