The former U19 international defender scored what proved to be the deciding goal in Tuesday's Scottish Cup replay at Motherwell, earning his side a fifth round tie at home to Hibs.
Aberdeen have one of the best youth academies in Scotland with Fulham and Wigan recently signing up teenagers from the Dons before they've made 30 first team appearances. Last week Ryan Fraser knocked back a new deal despite only breaking through this season with a trail of clubs including Swansea and Celtic showing interest.
Shaughnessy made his sixth first team appearance in the win over Motherwell and fully intends making his stay in the north east of Scotland a long-term arrangement.
Last week he signed a two-year extension to his Aberdeen deal and is delighted with the way his career has developed since signing from Salthill Devon.
"When I signed my previous contract for two years, my main aim was to push on and get close to the first team," the defender explained. "That's happened, so when I was offered another two years, it was an easy choice for me.
"I don't see many better places to develop while getting a chance in the side. I understand Ryan's decision, but it's each to his own.
Shaughnessy added: "It's not been a bad week and it's good to end it with the goal that takes us through."
