The fun-loving mechanic's family members have been plagued with financial difficulties in recent months, but AJ has since been attempting to help them out by getting his own job.
Next week's episodes also see AJ step in with cash for a family mortgage payment at the last minute, and Sharma told Inside Soap that he expects his resourceful alter ego to solve even more problems in the future.
Sharma commented: "AJ is such a contrast to the rest of the Masoods - he's the clown who loves to play. I love all his larking about. But while he's definitely the family rebel and is a lot of fun to be around, he's also doing what he can to help out with the money problems.
"AJ is a little bit of a hippy, and the word 'job' isn't really in his vocabulary - he's got a real wheeler-dealer, Del Boy aspect to his character.
"But when the going gets tough, AJ will step in to help his loved ones - and while he will probably never take the conventional route, he'll always get something sorted out in the end."
The actor also joked that his mother is taking the credit for his EastEnders part.
He said: "My mum watches EastEnders religiously and has always said I should play Masood's brother. I've worked with Nitin Ganatra, who plays Masood, on quite a few sketch shows, so mum has known him for years and always thought we'd make a great comedy duo.
"So far, exactly what she thinks should happen to AJ has happened - and now she reckons it's all down to her!"
EastEnders continues tomorrow (November 1) at 7.30pm on BBC One.
