The former Emerging Ireland and Ireland U20 back has dovetailed well with Francis Saili in the centres and the duo both crossed for first-half tries in their final day win over Scarlets.
And while Anthony Foley's side will be disappointed to have missed out on the top four - Scannell hopes the future is bright for the province.
"Coming into the season I was hoping to pick up a few games here and there, I got a few starts at the beginning of the season and I was just trying to build on those and enjoy every game I got," Scannell said.
"I haven't really looked back since, I've played most games since and it's been a great learning curve for me personally.
"There's a lot of academy lads coming through that have signed on for next year with a lot of games under their belt throughout the season so we've a good crop of young talent coming through. It's looking good."
Playing alongside a former All Black like Saili is always going to help and Scannell admits he has learned a great deal off his midfield partner.
"He's a world-class player, he's capped by the All Blacks and when he was signed I just wanted to learn off a player of his calibre," Scannell added.
"We've played a lot together in midfield this year and I've learned a lot from him, too, I really enjoy playing with him. He's a really exciting player and he was great again (on Saturday) and we work well together.
"We're both looking to build for next year. He's just coming out of his shell, he's a new guy, he's trying to get comfortable with the lads around him and he's started to do that since Christmas.
"He's playing some really good rugby and we hope to build on that partnership over the next few seasons."
