That's his brother. The poster's name is Sanjay Vakil. I think he's saying - look at my brother. He is so successful and intelligent. Unless you have won the putnam (his bro was a 4 time putnam fellow), you have no right to be bolder than him.
As an aside, I think Sanjay has an inferiority complex or can't see outside of his immediate circle who knows his brother.
