The situation
A payment provider was reconciling transactions in overnight batches, delaying merchant payouts and masking failures for hours.
The challenge
Millions of daily transactions across card networks, banks, and wallets had to match perfectly, with full audit trails and zero tolerance for double-payouts.
What we delivered
We built an event-driven reconciliation engine with idempotent ledger writes, streaming mismatch detection, and an operator console for exception handling — deployed on Kubernetes with strict SLOs.
