FAQ
What technologies do you use for backend development and API integration?
I specialize in building scalable backend systems using Node js and Express js. For database management, I work with MongoDB, PostgreSQL, and MySQL. I also integrate third-party services like payment gateways (Stripe/PayPal) and modern AI APIs (OpenAI/Claude).
Can you fix existing bugs in my Node js API or Express backend?
Yes, absolutely! If you are facing any errors, routing issues, middleware bugs, or authentication failures in your current Node js API, I can debug and fix them fast to ensure your backend runs smoothly.
How do you secure the REST APIs and user data?
Security is my top priority. I implement secure authentication and authorization systems using JWT (JSON Web Tokens), OAuth, role-based access control, password hashing (bcrypt), and proper HTTP headers to keep your web backend system fully protected.
Will you provide API documentation for frontend integration?
Yes, definitely. I provide clean and comprehensive API documentation using Postman or Swagger. This makes it incredibly easy for your frontend developer (React, mobile app, etc.) to integrate the REST API seamlessly.
Do I need to provide anything before placing an order?
It is highly recommended to message me before ordering. Please provide a brief overview of your project requirements, database preferences, or any specific API endpoints you need so we can design the perfect architecture for your application.
