hey im a jr software dev, somehow it seems like all my coworkers produce shit code 24/7. They are either trying to get it done as quickly as possible or they are lazy, or they are just clueless. They basically take the entire sprint to fix the new defects their features introduce. At first when I joined the team as a jr I didn't know exactly what their code did, now that I have been working in the codebase for 9 months I can clearly tell the code quality they are producing is just shit. what should I do? Basically their shit code gets through code review with just cosmetic changes, but the maintainability/robustness etc. is usually just enough to meet the AC's the next one to work off their feature is doomed since everything is hard-coded bs copied and pasted from features developed 10 years ago by another shit coder.
