I'm a backend developer as well (or maybe full-stack, hard to say) and I switched my 4k to 1080p long time ago, because it wasn't worth it. On the other hand I like good viewing angles and nice colors. Unfortunately the latter isn't too good in basically every laptop I tried and... my current monitor (eh).
Full-stack dev here, running 1x1080 23" (top) + 3x1440 27". No real interest in moving to 4k, 1440 is the sweet spot for my workstation. The only problem... need more monitors!!
