So, I had to listen very badly in a scrum about my poor code quality. Just because I haven't used the latest version of the library in my gradle build file, I haven't used DTO in the response of few endpoints in the controller class instead I used entity,... Etc was the mistake.

I admit that I have a long way to improve myself and there is a lot to learn, but there should be a proper way to escalate the situation rather than publicly pointing out mistakes rudely.

He is a senior with 10+ years of experience who badly told me in the scrum and not only that whenever there is a change needed in my PR he takes the screenshot and puts it in our dev team group and shows the mistakes and gives the suggestions instead of writing comments on the github PR.

Not only that, if I inform in the daily updates that I took 2 hours for this and that task, he says it should be done in 20 to 30 minutes.

Upper management has given him a lot of respect because he is knowledgeable and knows the stuff but it doesn't mean he is entitled to behave like this and demoralise other juniors.

The matter is cool now but this incident happened to me a few months back and those days were really toxic for me at work.
