No surprise at all and I'd challenge you to find any backend task that LLMs don't improve working on as much they do frontend. And ignoring that the parent comment here is just ignorant since they're talking about the web like it's still 2002. I've worked professionally at every possible layer here and unless you are literally at the leading edge, SOTA, laying track as you go, backend is dramatically easier than anything that has to run in front of users. You can tolerate latency, delays and failures on the backend that real users will riot about if it happens in front of them. The frontend performance envelope starts where the backend leaves off. It does not matter in the slightest how fast your cluster of beefy identical colocated machines does anything at all if it takes more than 100ms to do anything that the user directly cares about, on their shitty browser on a shitty machine on tethered to their phone in the mountains, and the difference is trivially measurable by people who don't work in our field, so the bar is higher.
