FAQ
What do you need from me to get started?
I need a clear description of the functionality you're looking for, any example data models (e.g., User, Product), and whether you'd like in-memory or database storage. If you have a Postman collection, mockup, or GitHub repo, that’s helpful too.
Will you include Swagger or Postman documentation?
Yes — Swagger UI is included in the Standard and Premium packages by default. It provides a visual interface for exploring your API. If you prefer Postman, let me know and I’ll include that instead.
Can you integrate my API with a real database?
Yes — the Premium package includes PostgreSQL integration. I can also work with MongoDB or other databases upon request. If you're not sure which one you need, I'm happy to advise.
Can you deploy the API for me?
The Premium package includes basic Docker support, which you can use for local deployment. If you need cloud deployment (e.g., Render, Fly.io, Heroku), message me first so I can assess scope and provide a custom offer.
