React on the front-end because of eco; Fastify on the backend w/ Postgres. I host React w/ Remix for light-duty SSR, but real work gets done on the backend. I'm moving away from metaframeworks as single solution -- they're easy, but keeping biz logic on the be makes it much easier to swap out fe and better for testability IMO. I'll prob shift over to Solid once / if Start ever ships, else Qwik.
