How I destroyed the Caro-Kann on move 11! All theory!

I recently played a 90+30 game against a 1600 rated player. I knew it would not be hard but I had to focus. Luckily for me, he fully entered my prep and I was comfortable from the opening. I saw a tactic early on and the endgame was kind of hard to play...

After nearly 3 hours of play, this great game ended. What did you think? Did you spot some tactics?
