Banking, FinTech & Digital Payments Engineering

Q: How do you handle double-entry accounting in FinTech applications?

We implement an immutable, event-sourced double-entry ledger where credits and debits must balance to zero for every transaction, backed by cryptographic hash chaining for audit integrity.

Q: Can you integrate local payment rails such as UPI, SEPA, ACH, and FedNow?

Yes. We build native connectors for UPI (India), SEPA (Europe), ACH & FedNow (US), and Faster Payments (UK) with automated reconciliation.
