The Challenge of Absolute Scale
Fintech Horizon was processing 2,000 concurrent transactions per second at peak — and visibly buckling under the load. UI stutter, failed transactions, and 400ms+ latency spikes were costing them clients and credibility in a sector where milliseconds define trust.
We began with a full systems audit. The monolith was the culprit: a single Node.js process handling auth, transaction processing, fraud detection, and reporting — all in one thread. The fix wasn't incremental; it required a full architectural rethink under a live production environment.
