A big part of this is QA flagging the bugs. Humans make mistakes, and testing is there to catch them. The goal is not to ship the bugs to the customer, not to never make mistakes.

This does not mean that there is nothing you can do to prevent bugs, but try to let go of the idea that bugs should never reach QA. That's what they're there for, and if you add another layer of QA between your work and them, you've basically doubled the work done without improving anything that gets shipped to the customer. And all for the sake of your ego to never have a sprint go wrong.
