Since you won in 26 moves, not in much that really mattered? ;)

It all looks quite crushing. Perhaps there's a quicker win somewhere.

They say after 11.Nd7, he'd be better.

Maybe. It's a perfectly playable position, though, and one where black has to play more accurately than white.

Up a pawn, I drew with White in:

I exchanged rooks and transformed the position thus:
8/1b3p2/4kp2/p1p4p/P1P1PPpP/3K2P1/1P2B3/8 w - - 0 1

You appear not to have posted any moves for that game, so it would be difficult to tell you where you went wrong.

After an exchange of rooks, the winning attempt would be to create a passed pawn on the queen side. The doubled pawns on the king side should also slightly improve White's chances. If you don't win these positions it can be because too many pawns are exchanged giving Black the chance to sacrifice to eliminate your pawns. In that context White doesn't want to be left with just an h pawn.

You played a4 which denies you a pawn break on the queen side. The pawn should be on a3 and the King on c3 to support playing b4. The Bishop perhaps on d3 to defend the e4 pawn, but you didn't need to move the king side pawns.

Another thought on this, assuming the pawn is on a3 is that if you distract the Black King from staying on e6 because of the threat of a passed c pawn, that the cheapo threat of Bxg4, followed by h5-h6-h7-h8Q might work.

As a superficial assessment the d5 pawn is going anyway, so you might as well try to get something for it, such as making the Bishop on a2 a useful attacker of f7.

Also if .. Bxd6, White could take it and gain the Bishop pair, while if cxd6, Black is saddled with an isolated pawn. None of it decisive, but enough perhaps to support a "white is better" assessment.

By Ba5 presumably.

Should Black play 20. d6 Nxe4 ? Then if 21. dxe7 Nxd2. Perhaps that Knight is now trapped so White wins the exchange. White has to know that 20. .. Nxe4 doesn't work, otherwise 20. d6 is a gamble.

Why gamble? I didn't see 20...Nxe4 at first, but Hadi Ghorbani, the brother of IM Ghorbani, said it loses too, as I was anxious

If you play a move that looks right without in depth calculation when your opponent has the option of a sequence of captures in response, you are gambling that your positional feel and assessment will ensure that something refutes it. It's something you may need to be able to do in blitz and when short of time.
