I just reviewed your chess.com’s profile and found some mistakes. These mistakes are easy to fix, let’s watch one of your recent chess game first.
Opening Suggestion:
with white pieces, you are playing Giuoco Piano, which is good opening, but I suggest you to play the Bishop Opening, Bishop Opening is aggressive and limits your opponent and the plans are very clear and straightforward, which is to attack Black’s king.
With Black pieces, you are playing with Caro Kann, which is good and sound opening. I suggest you to stick to this opening until you get 1500 rating.
Middlegame Suggestion:
In the middlegame, you often blunder a piece, but in one recent chess game you blundered a queen, which is terrible mistake. You should not blunder any piece or pawn.
Do you know how to stop blunders? the simple answer is that you must look at the chess board and check which pieces or pawns are unprotected, when you see unprotected pawn that is where you blunder. So please keep this tip for avoiding blunders.
So my suggestion is to learn how to avoid blunders, and learn tactical motif. For learning tactical motif you may visit: https://chessrewards.com/chess-strategies-and-tactics/.
Endgame Suggestion:
There are only two plans in the endgame, one is to create weakness, and second is to create a passed pawn. Now it’s up to you how do you achieve this goal in your next endgame.
Conclusion:
One more thing I noticed that you are playing bullet a lot, I warn you that at your level bullet will destroy your basic chess understanding, play blitz or rapid chess game for improvement.
