About this service
Summary
FAQs
What exactly will I get from this backend service?
You’ll get a NestJS backend with REST endpoints for your core features, a PostgreSQL database schema with Prisma migrations, and a short README explaining how to run, configure, and integrate the API with your frontend.
What do you need from me before starting?
I need a description of your product, the main entities you want to store (for example users, orders, bookings), any existing database or API, and information about your hosting environment or preferred platform.
Does this include authentication and roles?
Yes, this service can include user authentication (for example email/password with JWT) and basic authorization rules, such as separating admin and regular user endpoints, as part of the scoped API.
Can you connect this backend to my existing frontend?
Yes, I can design the API to match your current frontend needs or collaborate with your frontend developer to define request/response shapes that keep both sides simple and maintainable.
What if I need more endpoints or complex features?
The fixed price covers up to 4 main entities and around 10–12 REST endpoints, plus a standard auth flow. If you need more complex logic (for example reports, multi-tenant setup, heavy background jobs) or additional endpoints, we can adjust the scope and price or create a separate follow-up project.
What's included
REST API with CRUD endpoints
A structured NestJS REST API with typed endpoints for creating, reading, updating, and deleting your core resources, including proper error handling and input validation.
PostgreSQL database schema and migrations
A relational database schema designed in PostgreSQL with Prisma models and migrations, so your data structure is versioned, consistent, and easy to evolve over time.
Authentication and authorization setup
Implementation of user authentication (for example JWT or session-based) and basic authorization rules, wired into your API so protected routes and roles are enforced server-side.
API documentation and developer handover
A concise README and endpoint documentation describing how to run the backend, environment variables, and how each API route should be used by your frontend or other services.
