Scaling a FinTech Neobank to 2 Million Active Accounts

The Business Challenge

Apex experienced rapid user growth that overwhelmed their ledger transactions, resulting in slow balance reconciliations and API timeouts.

Our Architectural Solution

We designed an immutable double-entry ledger engine powered by FinCore, with automated idempotent processing, asynchronous queues, and PCI-DSS compliant vaulting.

The Measurable Impact

Supported 12,000 concurrent transactions per second with sub-50ms latency and zero financial reconciliation discrepancy.
