I'm a senior software dev and have built a shitload of tools and scripts that are command line only. I've been told that I'm a really great developer, and I have a knack for figuring things out, even when there's no documentation.
For the life of me, I absolutely cannot wrap my head around frontend shit. Like, I can do markdown just fine. HTML? CSS? Any of the popular frontend UI frameworks? I just seem to have some sort of conceptual and motivational block that prevents me from figuring out how to make those accursed fucking frontends.
It's such a different form of software development. I wish I could wrap my head around it, but I've accept that I'm not ever going to be a frontend dev. I just write server side stuff and scripts. I apologize if you ever have to use my software :(
