    Challenge

    Small projects need a simple API. Writing boilerplate (CRUD, auth, validation) takes 2–3 days each time.

    Solution

    UI to define schemas (fields, relations, validation). Backend generates NestJS resolvers, MongoDB schemas, GraphQL types, REST endpoints, Swagger docs — all on the fly.

    Results

    Time to set up a new API: 2 days → 30 minutes. Zero-code for 80% of use cases (CRUD + auth).
