Several comments.
Probably better to "enclose" the top right corner with R-13 or R-14. You don't need to focus on your two stones in the bottom right, the bots tell us.
Probably better at O-17, to work with the Black stones on the right side.
Small. Very likely mistake.
Obviously bad.
Perhaps a memory from a different position. I assume that you invaded with the idea of either living in the corner or connecting to the right side.

stone bad, as it forms an empty triangle. One problem with
is that it looks to possible Black life with stones on S-02 and S-04. But if Black plays at S-04 and White plays at S05. then

, Black lives by playing on R-03. That way
still looks bad.
I know that you have to read ahead for this, but it's pretty much a one lane road and only 7 moves deep.
Aside: You do not have to invade right now. Invasion is one way to capitalize on your strength in the opening. But, even though you are ahead, you risk losing your advantage by getting into fights before you have a big advantage. Another good play for
is O-17. Let White make some more mistakes before getting into a fight.
White makes another mistake, going after the small rather than the large.
You shouldn't follow your opponent around when your opponent is strong. Don't follow your opponent when your opponent is weak. (By comparison, your opponent is worse than you during the opening.
) Make the bigger play, O-03. You don't want to take the
stone, anyway, as that would end up making the
stone good.
The worst has come to pass. However, best play is above the SDK level. Fortunately, the Black corner is small enough to sacrifice, but how to do so, or to threaten to do so, takes a good bit of skill. The double peep at O-03 may be best, but the play is difficult. This illustrates the problem with seeking fights before you have built up a lead.
A minor error, but the capture is better.
White likes to make small plays. Possibly from greed, trying to take away potential Black territory.
Giving White outside strength is questionable. For one thing, it may help White's thin extension at C-11. O-17 still looks good. More importantly, it will hinder possible invasions by Black on the bottom side.
Fortunately, White doesn't know what he is doing.
The peep at F-03 looks good. Also, the solid connection makes the White sagari at E-01 sente, while the handing connection makes the sagari at A-06 sente. The sagari at E-01 is worse for Black.
White does not know what he is doing.
A-03 makes two eyes.
Given the E-02 and E-01 stones, this play does not make a base for Black. Instead of a play on the bottom side, it is probably better to push through at O-04, which threatens the White stones in the bottom right, which do not yet have two eyes.

Don't follow your weak opponent around. Push through at O-04.
The two step hane is better. A useful tesuji.
Back to O-04.
This might have been a good play earlier, to separate and attack two White groups. But now it's just small.
White does not know what he is doing.
Strengthens White and is small, besides. O-04 remains big, as usual.
White has handed Black the game on a tray.
Probably not best, but a good play.
Good.
Again, White goes small.
Don't follow a weak opponent around. Jump to M-06 combines attack and defense.
Small. Jump to M-06.
Starts a fight where Black is weak. Jump to M-06.
(Black 101). Threatens the cut at G-05, but Black is too weak locally.
Good idea.
M-06 is still good. The game play is not as good for defense, nor as good for attacking White on both sides.
Not a bad move, but feels like an attempt to save two stones. By contrast, the keima, J-08, threatens a large White group, and if the attacks moves towards the right, may end up attacking the weak group on the right, as well.
Eye off the ball. Black must keep the White groups separated. Better to play L-07.

I am going to stop here, even though Black is well ahead. Three main points:
1) Same as before. Keep you opponent's attackable stone separated, as a rule.
2) Do not follow a weak opponent around. (That's all of your opponents right now.
)
3) Psychologically, it seems to me that the desire to save your own weak stones led to poor decisions. In particular, running with your two stones with Black 107, while not a bad play in itself, made difficulties for yourself, not your opponent.

Edit: A few more comments.
(Black 133). Bad decision to save a few stones.
,
Not fatal, but it feels like Black is trying to save his stones, not capture the White cutting stone or other stones.
A failure to count dame?
Does not gain a dame. Sigh!
Saves the small, sacrifices the large.
Too soon to resign. Black can still goof.

The reading failure aside, White lost his advantage by a failure to attack.
