FAQ
Can you build the backend for my existing frontend/app?
Yes. Send me your frontend (React, mobile app, etc.) or API requirements, and I'll build a backend that connects to it seamlessly.
Do you build the database as well?
Yes, I design and set up the database schema (PostgreSQL, MySQL, or MongoDB) as part of the backend.
Will I get API documentation?
Yes, I provide clear API documentation (Postman collection or Swagger) so you or your team can understand and use every endpoint.
Can you integrate third-party services (payments, email, etc.)?
Yes — Stripe, PayPal, email services, and most REST/third-party APIs can be integrated into your backend.
Is the code secure and production-ready?
Yes. I implement JWT authentication, input validation, and follow security best practices so your backend is ready for real users, not just a demo.
Do I get the full source code?
Yes, full source code is included with every package.
