Real-time transaction risk decisions
A low-latency risk scoring platform designed for high transaction volumes and resilient operations.
Assignment context: Discover Financial Services
The challenge
Transaction risk decisions have to be made while the customer is still in the flow. The platform needed to combine multiple signals quickly and remain available as demand increased.
The approach
The assignment included a device intelligence service and integration with external risk profiling. Performance analysis and tuning focused on distributed cache behaviour. A resilient messaging architecture was developed with network, infrastructure and operations teams.
The value demonstrated
The work illustrates a practical approach to real-time systems: measure first, address the bottlenecks, and design resilience into the services around the decision engine.
