FAQ
Can you build a backend for my mobile app?
Yes! I build RESTful APIs specifically designed to power mobile apps (iOS/Android). I'll provide full API documentation and a Postman collection so your mobile team can integrate easily.
Can you integrate payment gateways like Stripe or PayPal?
Absolutely. I've integrated Stripe, PayPal, and Razorpay into multiple production apps. This is available in the Premium package or as an add-on.
Will you write tests for the API?
Yes, I include unit and integration tests (Jest/Pytest) in Standard and Premium packages to ensure your API is reliable and bug-free.
Can you work with an existing codebase?
Yes! Just share your repository and I'll review it first. I can extend, refactor, or fix bugs in an existing backend.
Is the code production-ready?
Yes. All code follows best practices: environment variable management, error handling, input validation, security headers, and proper logging , ready to deploy.
