REST API & Backend Development (Node.js / Python)

I build secure, well-structured REST APIs and backend systems that are ready to integrate into real applications. From authentication and database design to third-party integrations and automated testing, I focus on backends that are reliable, maintainable, and built around your business needs.

What I can build for you

REST API development: Clean endpoints and organized route architecture using Node.js, Express.js, or Python frameworks.

Authentication and authorization: JWT authentication, password hashing, and role-based access control.

Database integration: MongoDB or PostgreSQL integration with structured data models and reliable queries.

Validation and error handling: Input validation, consistent error responses, and defensive coding practices.

Third-party integrations: Connect your backend to external APIs and services.

Real-time functionality: WebSocket or Socket.IO features when your application requires live updates.

API documentation and testing: Postman collections, endpoint documentation, and automated testing where appropriate.

Deployment preparation: Environment configuration and support preparing your backend for deployment or CI/CD workflows.

My approach

I prioritize readable code, sensible architecture, secure handling of credentials, and clear documentation. You’ll know what is being built, how the API works, and how to integrate it into your application.

Deliverable: A backend or REST API scoped to your requirements, with agreed features, documentation, and testing included in the package.
