Looks Like This Service Is On Hold
I will develop a production ready node js rest API with jwt authentication
Al Amin Sheikh
About this gig
Most web apps fail not because of the frontend but because the backend API is slow, insecure, or poorly designed.
I build production-ready REST APIs using Node.js, Express, and TypeScript with secure authentication, scalable architecture, and clean maintainable code.
I'm a full-stack developer specializing in Node.js, Express, PostgreSQL, MongoDB, Prisma ORM, and JWT authentication. Every API I build is designed for performance, security, and scalability.
WHAT I BUILD
- REST APIs with GET, POST, PUT, PATCH, DELETE endpoints
- JWT authentication with secure login and refresh tokens
- Role-based access control (RBAC)
- PostgreSQL + Prisma ORM relational databases
- MongoDB + Mongoose flexible schemas
- CRUD operations with validation and proper HTTP responses
- Middleware architecture, CORS, rate limiting
- Swagger / OpenAPI documentation
- File uploads and third-party API integrations
- Deployment-ready setup for Vercel, Railway, Render
HOW I WORK
- Review your requirements
- Design the API structure
- Build clean TypeScript backend code
- Test endpoints and deliver with documentation
Message me before ordering and Ill confirm the best solution for your project.

FAQ
Q1 — What information do you need to start building my API?
To start, I need: • A short description of your application • The backend features required (auth, data storage, uploads, etc.) • Your preferred database (PostgreSQL or MongoDB) • Any existing frontend or codebase to integrate with If you’re unsure about the requirements, message me and I’ll help
Q2 — Will the API work with my React, Next.js, or mobile app?
Yes. The APIs I build are REST-based and frontend-agnostic, meaning they work with React, Next.js, React Native, mobile apps, or any client. You’ll receive Postman collections or Swagger documentation so your frontend team can integrate quickly.
Q3 — Do you use TypeScript or JavaScript?
I usually build APIs with TypeScript because it improves maintainability and catches errors early. However, if your existing project uses JavaScript, I can work with that for consistency.
Q4 — Should I choose PostgreSQL or MongoDB?
It depends on your data: • PostgreSQL – best for structured relational data (users, orders, transactions) • MongoDB – best for flexible or document-based data If you’re unsure, I’ll recommend the best option for your project.
Q5 — Will I own the code?
Yes. You receive full ownership of the source code via GitHub. I also provide a README with setup instructions, environment variables, and deployment guidance for platforms like Railway, Render, or Vercel.
Q6 — Can you add authentication to an existing API?
Yes. I can integrate JWT authentication, refresh tokens, and role-based access control into existing Node.js / Express APIs. Please share your codebase before ordering so I can review the scope.
Q7 — What does “production-ready API” mean?
It means the API is ready for real-world use, including: • Proper error handling and validation • Secure JWT authentication • Clean architecture (routes, controllers, services) • Environment variable configuration • Swagger / Postman documentation This ensures your backend is secure, scalable
