I can understand feeling a certain amount of guilt about issues making it out to production. However I personally feel like the overall quality of a product should not be owned by an individual QA but by the entire team instead. A lot of the "shift left" methodology addresses this.

some of the things that we've done:

• keep all work small and safe (as possible).
• use feature flags
• BA, QA, SE all agree to basic acceptance criteria before work dev work starts
• switch to trunk based development

This would likely take buy in from all stakeholders though. Good luck.
