Need a dependable backend to power your web application? I will develop Express.js APIs and backend services using TypeScript, with a focus on organized server-side functionality, clear API structures, reliable data handling, and maintainable code.
I can build an API from scratch, extend an existing Express.js backend, connect your application to MongoDB, or implement the server-side functionality required by your frontend.
My approach is to structure backend functionality so that it remains understandable and practical to expand as your application grows. This includes organizing routes, business logic, data access, validation, and API responses in a way that supports future feature development.
I can help with:

Express.js backend development
REST API development
TypeScript backend development
API endpoint creation
MongoDB integration
CRUD functionality
Business logic
Authentication and authorization
Request validation
Error handling
Third-party API integration
Existing API improvements
Backend feature development
API bug fixing and refactoring

I can also connect the backend to a Next.js frontend to create a complete full-stack application.
Whether you need a small API for an existing application or a backend foundation for a larger product, I can build the server-side functionality around your actual requirements.
If you already have API documentation, database requirements, frontend code, or an existing backend, share those materials and I can work within the current project structure.
