FAQ
How much does it cost to build a Node.js REST API?
A small API for one resource starts at $95. A 20-endpoint API with auth and tests is $295, and a production API with integrations and deployment is $795.
Is NestJS better than Express for a backend?
For most growing products, yes. NestJS gives structure, dependency injection and TypeScript by default, so the code stays clean as it grows. I build in Express too.
Can you integrate Stripe, Shopify or Twilio into my API?
Yes. I've integrated Stripe, Shopify, Twilio, Firebase, Google Maps, Microsoft Graph, SendGrid, GoCardless, OAuth providers and 8 shipping carriers.
Can you build an API on my existing database?
Yes. I can build on your existing PostgreSQL or MongoDB database or design a new schema. Share the schema or read-only access.
Do you write API documentation and tests?
Yes. Every package includes Swagger or GraphQL schema docs, and Standard and Premium include tests for key endpoints.
Can you integrate a legacy SOAP or XML system?
Yes. I have shipped SOAP and XML integrations and wrap them in clean REST or GraphQL endpoints, so your apps talk to old enterprise systems without touching XML.
Can you migrate my Express API to NestJS?
Yes. I migrate module by module and keep endpoints compatible, so your frontend keeps working. Message me with the repo for a quote.
