Frequently Asked Questions

Can you build a per-second billing system?

Yes — I shipped exactly this in the Dil ki Baat platform. Every second of a voice call deducts from the user's wallet atomically, with zero discrepancy across all transactions even during network failures.

Do you handle Razorpay webhooks securely?

Yes — webhook signature verification, idempotency keys to prevent duplicate credits, and dead-letter queue for failed events. All production-tested.
