Precision Under Pressure
The second phase of Fintech Horizon focused on the mobile layer — a React Native application serving 600k active users that had never been properly performance profiled. Render times averaged 280ms. Users were abandoning transaction flows at a 34% rate.
We introduced a full render audit, eliminated 18 redundant re-renders per transaction flow, and implemented optimistic UI updates that made the app feel instantaneous even over degraded mobile connections.
