I’ve been there. It sounds like you’re starting to blame yourself for their failings. You’re not sure if you’re a little crazy or they are. They’re gaslighting you. Get. Out. As. Soon. As. Possible.

If they’re using your valid concerns as issues on performance reviews, then the company values making low quality software, not their employees. Get out of the sausage factory and get into a place that values their employees and product. You’ll be much happier.
