Complete Five Node.js Backends

I already generated the core logic for five separate management back-ends with ChatGPT and documented every endpoint, model, and workflow in a detailed specification. Each project is written in Node.js and currently connects to MongoDB in parts; some modules also point to an SQL layer—whether that is MySQL or PostgreSQL you will confirm once you spin the code up.

So far, the skeleton routes, authentication hooks, and the first pass of the User-accounts and Order-management models are in place. What I need from you is to take one of these services, walk through the dev document, clean up the existing code, finish the remaining endpoints, wire up the proper database calls, and hand back a fully functioning API with unit tests and basic deployment instructions.

Deliverables per system
• Complete Node.js source (ES6) matching the spec
• Working Mongo/SQL integration with migrations or seed scripts
• Postman (or Insomnia) collection covering every route
• Minimal README explaining environment variables and start commands
• Passing test suite that proves the User and Order flows

I am bringing on five developers—one per backend—so efficient, well-structured pull requests and clear commits matter more than flashy dashboards. If you’re comfortable debugging someone else’s GPT-generated code, tightening it up with Express, Mongoose/Knex, and Jest or Mocha, you’ll fit right in.
