I am a bad software developer and this is my life

Sorry to hear that, it sounds like a tough situation.

My suggestion would be to speak with a professional career coach or mentor (I am a career mentor and coach myself). It sounds like you have a good background, but something is going wrong in the hiring process.

The hiring process today is complex, and many job applicants will get auto-rejected for simple reasons. When you work with a coach, they can show you which red flags are in your profile or CV/resume, and you will be able to fix them together.
