Was thinking my fella is in his mid thirties, and for a while, was a nonnaffliated case. A contractor for whatever family wanted to use his services. A fence and a safe cracker would be perfect for a neutral party. Until maybe a few years ago when the Serpeverde family talked him into helping with silencing a "Rat" and to make sure  he didn't get pinched in the Auror investigation he joined up officially 

He's likely got maybe 9 to 12 years of experience. Having done this since his late 20s.

It's a specific experience, though, so it's not like he's a super experienced gangster.

What do you have in mind for his safe cracking techniques? I'd image any safes he cracks would have multiple layers of magical protections so that a simple [i][b]Alohomora[/b][/i] Unlocking Charm wouldn't quite do it XD. I'd imagine his skills could be put to use against many types of magical barriers besides just safes, so he'd be extremely valuable to the Family. Unless you're thinking the safes use like special magical-tech locks that he breaks through.
