Real-time fraud scoring for checkout
Proposed
Risk Platform · Updated Jun 21
Requirements
Score every checkout in <120ms p99 and block high-risk transactions before authorization.
Solution overview
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 be built: the requirements, the design, the trade-offs, and the rollout. It’s the document a delivery team and its architects align on before the first line of code.

Diagram first
Every design leads with a live Mermaid diagram, and the catalog can be browsed as diagram panels.
Complete by default
Requirements, detailed design, trade-offs, non-functionals, risks, and rollout in one template, so nothing gets missed.
Signed off, on record
A named reviewer accepts, rejects, or requests changes with a checklist, and every version is kept.
