Jax Pavan was one of the 582,797,754 Human males named Jax Pavan on Coruscant. He flew for the Rebel Alliance in the Rougue Squadron. In fact, he was so good he got Wedge Antilles's autograph after the battle of Endor, which he kept under his pillow and looked at it every night before he went to sleep. Uh....interesting.
He was known as "Repairman" Jax, which was odd because he was a pilot, not a repairman.
