REST / GraphQL API Backend

A production-ready REST or GraphQL API with authentication, rate limiting, OpenAPI docs and automated tests. Custom backend development from $900 to $2,200 in 8 to 18 days.

The problem

Startups and agencies often have a mobile app, a website and a partner who all need the same data, yet the logic lives inside one codebase or a no-code tool that cannot be shared. Each new client means copy-pasted endpoints, undocumented behaviour and security gaps such as missing rate limits or leaked IDs. Hiring a backend engineer for this takes months in Dubai or Bangalore and costs far more than the API itself.

What we build

We design and build a clean REST or GraphQL API in Node.js or Python/FastAPI with JWT or API-key authentication, role-based permissions, validation, pagination, rate limiting, webhooks and versioning, backed by PostgreSQL. Claude Code and Cursor generate the schema, resolvers, OpenAPI spec and integration tests from the agreed data model, GitHub Copilot fills in the boilerplate, and we hand-review the authentication and data-access paths. The result is a documented backend your frontend and partners can integrate in an afternoon, delivered with full source code at a fixed price that never exceeds $2,500.
