FAQ
Do you provide API documentation for frontend integration?
Yes! I can provide a Postman collection or interactive Swagger/OpenAPI documentation so your frontend team can easily consume the endpoints.
Can you connect this backend to a React or Next.js frontend?
Absolutely. I build REST APIs with proper CORS configuration, ready to be consumed by any frontend framework like React, Next.js, or mobile applications.
Can you optimize slow PostgreSQL database queries?
Yes, I analyze query performance, set up proper indexing, optimize Django ORM calls (avoiding N+1 queries), and tune database structures for fast response times.
Will I get the full source code?
Yes, all packages include the complete, well-commented source code with setup instructions.
