You sound like you are siloing your developers by having individuals in charge of stories and also being the gatekeeper to production. You should be baking TEAM review and TEAM approval into your development process especially if you want to start doing continuous deployment, and it sounds like you have jumped off a cliff without a parachute if you have eliminated dedicated QA...

If your team decides they want to involve some public shame in their processes that's one thing but it's extremely dangerous for any manager to introduce themselves and it should never relate to production.

The team owns the code.
