I prompted a personal financial dashboard a few months ago, simple javascript stack. It worked. Wanted to extend it, oh boy, what a mess. Migrated the whole thing to #Symfony yesterday. The tedious code migration parts were done by Claude and it did 90% properly. The trick was good slicing and targeted prompts. For tools that should work long-term: use the stack you are familiar with. Authentication, Frontend, Doctrine, everything was setup so fast, almost like magic.
