Coding CRUD and repeating patterns tends to be boring, however writing interesting logic in backend tends to be interesting.
Generated CRUD interfaces with basics like authentication etc is pretty much easy these days, whether Supabase, Hasura, PostgREST style self hostable stacks or just Firebase, even collaborative data structure basics for CRDTs don't need to be built each time and are available out of the box.
Frontend can get repetitive too, a lot of components keep getting built and redone differently, interesting stuff which makes the tech be core part of the product differentiator such as say how WASM is used at Figma is the real interesting part in frontend.
