I just had the same in the opposite direction (to an extreme degree, hand waving away an enormous amount of complexity). The blade of Dunning Kruger cuts both ways.

Though what you describe sounds awful too. Hopefully with the recent era of tooling and discipline on the frontend side, we'll see less of that.

Yes, that kind of arrogance can definitely come from the front-end side as well. I've just noticed a pattern with a certain type of back-end developer. Similar to the old XKCD physicist comic, there is a personality type that seems to think they can spitball an ad hoc solution to a problem that is better than the work of specialists in the field.
