Hi there! That's what we're working on with Retool (https://retool.com https://retool.com) It's, as you say, a "DB-backed" (or API-backed) front-end builder that's designed specifically for engineers. We don't store any data, and you can customize the front-end by importing your own React components or by writing JS. (I made it, so feel free to ping me if you have any feedback: david AT retool)
