The challenge
Northbeam's decade-old ledger system was buckling under transaction volume, with nightly reconciliation jobs taking hours and frequent data drift between services.
Our approach
We re-architected the ledger around an event-sourced, double-entry model with strict consistency guarantees, migrating traffic gradually behind a shadow-write pipeline to eliminate downtime risk.
