About this gig
Are you looking for a reliable, fast, and well-documented REST API or backend service? You're in the right place!

What I offer:
- Custom REST API development with clean, scalable architecture
- - FastAPI with automatic Swagger/OpenAPI documentation
- - Node.js & Express.js backend services
- - JWT authentication & secure endpoints
- - Database integration: PostgreSQL, MongoDB, SQLite
- - Input validation, error handling & logging
- - Well-structured, commented, and maintainable code
- - Postman collection or API documentation included
Why choose me?
- Fast delivery with professional quality
- - Clean code following best practices
- - Clear communication throughout the project
- - Post-delivery support included
Whether you need a simple CRUD API, a full authentication system, or a complex microservice, I've got you covered. Let's build something great together!

FAQ
What information do you need to get started?
I need a description of the endpoints you want, the data models, preferred tech stack (FastAPI or Node.js), and any authentication requirements. The more details you share, the faster we can get started!
Do you provide documentation or a Postman collection?
Yes! All packages include clear documentation. The Standard and Premium plans include Swagger/OpenAPI docs (auto-generated with FastAPI) and a Postman collection so you can test all endpoints easily.
Can you work with my existing codebase or database?
Absolutely! I can integrate with your existing project, database schema, or codebase. Just share the details before ordering and we will discuss the best approach for your needs.
