You will get a custom REST API or GraphQL API built with Node.js
Top Rated
Project details
A well-designed API is the foundation everything else is built on. A poorly-designed one turns every new feature into a negotiation with technical debt.
I've designed and built APIs for SaaS products, mobile apps, marketplaces, and third-party integrations. I write APIs that are intuitive to consume, fast under load, and structured so your team can extend them without fear. Whether you need a clean REST API, a flexible GraphQL layer, or both — I build it right.
What you'll get:
REST or GraphQL API built with Node.js (Express or NestJS)
Clean resource-based structure following industry conventions
Authentication and authorisation (JWT, API keys, OAuth2)
Request validation, error handling, and consistent response formats
Database integration (PostgreSQL, MongoDB, or MySQL)
Pagination, filtering, and sorting on list endpoints
Rate limiting and security headers
Swagger/OpenAPI documentation generated automatically
Built with the assumption that other developers will consume and extend this API — clean, documented, and predictable.
