David Murage
About this gig
Do you need a reliable Node.js backend or a professional third-party API integration?
I will build, fix, or integrate REST APIs using Node.js, TypeScript, Express.js, or NestJS. I can connect your frontend or business application to databases, payment providers, authentication services, webhooks, and other documented APIs.
My services include:
REST API development
Third-party API integration
Node.js, Express.js, and NestJS backend development
PostgreSQL and MongoDB integration
Authentication and role-based access control
Payment gateway integration
Webhook and callback implementation
Input validation and structured error handling
API testing using Postman
Technical documentation and code comments
Docker configuration and cloud deployment
I focus on secure implementation, maintainable code, proper testing, and clear communication.
Please contact me before ordering so I can review the API documentation, number of endpoints, existing codebase, database requirements, authentication method, callbacks, and deployment environment.
I only work with documented and authorized APIs.
