Real-time fraud scoring for checkout
In Review
Risk Platform · Updated Jun 21
Goal
Score every checkout in <120ms p99 and block high-risk transactions before authorization.
Design
Stream checkout events to a feature pipeline; a model service returns a score the payment gateway gates on.
Risks
Model latency under burst load; mitigated with a cached fallback score and circuit breaker.

What it is

Where a reference architecture is the reusable pattern, a solution design is how one concrete initiative will actually be built — the goals, the chosen components, the integrations, and the trade-offs. It’s the document a delivery team aligns on before writing code.

Goal to implementation
Ties business objectives to the concrete components and services that deliver them.
Reuses the catalog
Pulls in reference architectures, components, and standards rather than redescribing them.
Review-ready
Structured for architecture review boards — context, design, risks, decisions.
