Intelligent Trade Reconciliation at a Global Capital Markets Bank
The client's middle-office team was spending hundreds of analyst-hours per month manually investigating trade breaks. Ruvca built an NLP and ML pipeline that automatically classifies break types, predicts root causes, and routes to the right resolver — reducing resolution time by 60%.
Result: 60% faster resolution · 300+ analyst-hours saved per month

Predictive Maintenance for a Global Energy Major
Unplanned downtime on upstream assets costs tens of millions per incident. Ruvca's team built time-series anomaly detection models on sensor data from the client's production assets, enabling maintenance teams to act before failures occur rather than responding to them.
