Our most senior and most competent backend developer got fired, he got told he "wasn't committed enough". This dude did the most complex tasks really quickly (and competently), could configure the most boring stuff off the top of his mind, and brought great culture to the company from his previous 20+ years of experience. He was about to implement some cool automation stuff, and improved our processes a great deal.

Now he's being let go. I was fearing *I* would get fired because I'm much slower and less knowledgeable than this guy.

When I talked to him, he figured the so-called "lack of commitment" was because he had missed a few standups the last few days, and got late to today's standup.

Now the boss (who is a less experienced than this dev who was let go, but co-founder of the company) was changing the database credentials (which we somehow have access to) and had the product down for like half an hour because of it.

I don't think firing this developer was a wise decision at all, and that's putting it generously. What a shame. Now I'm also a bit scared because the responsibilities of this developer might likely fall upon me. But generally I think we're worse off without this guy, and getting someone as good as him will take time.
