FAQ
What technologies do you use for backend development?
I use node js (express js) and fast api to build fast, secure, and scalable REST APIs. I work with mongodb and sql databases, and can implement jwt authentication, role-based access control, and secure API architecture when needed.
Can you create CRUD APIs for my application?
Yes, I can build complete CRUD (Create, Read, Update, Delete) APIs using node js or fast api with proper database integration. All APIs are well-structured, secure, and ready for production and frontend integration.
Do you handle API integration between systems?
Yes, I can integrate multiple systems using REST APIs built with node js or fast api, ensuring secure data flow, proper authentication, error handling, and smooth communication between services.
Will my backend be scalable and secure?
Yes. I design scalable and secure backend architectures that follow best practices. This includes authentication, input validation, secure database handling, and protection against common API vulnerabilities.
Can you optimize performance for high-traffic applications?
Yes. I optimize APIs for high performance using efficient database queries, clean architecture, caching strategies (if needed), and proper request handling to ensure fast and reliable response times.
Do you provide documentation and post-delivery support?
Yes, I provide basic API documentation and post-delivery support to help you integrate and maintain your backend easily after delivery.
