The 20-year-old started the last five games of the Premiership campaign in Carr's absence through suspension and inujury.
That took 'Steo' to seven starts and four substitute appearances and he capped a season to remember by being called up to the full Irish squad for the friendly against Poland.
He is set to return to international duty tomorrow for Ireland's Under-21s in a friendly against Scotland.
"Stephen's done very well," said Steve. "He's a very good player, still very young and still has a lot to learn, as we all do.
"But that experience of coming in and playing those five games will stand him in good stead.
"Hopefully he'll also be involved more in the full Irish squad and that will help his development as well.
"It's been a very good season for him, he's pushing for that right-back spot and that's good, we need competition all over the pitch."
Stephen Carr believes Stephen Kelly's late run in the side will work wonders in terms of his development.
