As a primarily backend dev, one thing that has recently helped me with my design skills is to use page builders.

I’ve found that they’ve gotten really good over the last few years and the code they generate is actually pretty solid. I’m the kind of person where I think I can tell what good design is, but I can’t actually design it from scratch myself.

I recently bought a subscription to https://shuffle.dev/ which has a page builder for tailwind, bootstrap, material, and bulma and it’s saved me a lot of time and generated some really slick looking sites.

A $20 subscription is definitely a lot cheaper than a designer and is faster than waiting for a design and then building it yourself. I’m not affiliated with them in anyway, but would highly recommend it as a part of your workflow.
