Being able to read and write code in whatever language you claim to be proficient in on your resume is just table stakes imo. Being self taught I learned the whole team based development life cycle on the job. It was stressful. But it took maybe a month or two and I was proficient at git, setting up CI/CD, writing unit tests, and debugging things to just name a few.

I laud you being willing to teach a junior dev but I just find so many places are not open to hiring juniors at all.
