I thought I was doing reasonably well until after the exchange of Queens, when he launched a queenside pawn avalanche on me. In hindsight I guess I should have seen that coming, and maybe avoided swapping Queens, as I needed by Queen to try to pick off his pawns on the queenside
In the QGA, you should always try to get the pawn back (on the c-file). Once you lost all 3 defending pawns, there was very little you could do to stop that; he could not have marched down the board if your pawns were still there. Thus, it is probably a win for black regardless. The endgame didn't look awful for you.
In my humble (and disputable) opinion, play e3 and use all your power on the queenside earlier, to get rid of the pawns and even the count. It is way easier than trying to pick them off once his pieces are mobilized. Likely continuation after 4.e3 is his b4, then play a4 and you usually get your pawn back.
