Welcome to the world of software engineering! See, building software is more about people than code or technology. It is always a people problem.

Use this as an opportunity to improve your social skills. If you think your colleagues are sloppy, find a way to reach them. Learn how to give in-offensive feedback. That's invaluable for your career, no matter what you do.

Also, the resentment you feel towards others is likely resentment that you feel towards yourself (as you say yourself), so that is another area you have now the chance to use and grow.
