Technology
Built for scale and reliability
Microservices, event-driven processing, and a consistent ledger model. The same stack powers the payment gateway and Habit Money.
Microservices architecture
Bounded contexts and service ownership. Deploy and scale components independently.
Event-driven processing
Pub/Sub and message queues for async workflows, retries, and audit trails.
Message queues
Durable queues for payment events, webhooks, and settlement jobs.
Ledger consistency model
Double-entry ledger with idempotency and conflict resolution.
Fraud detection hooks
Pluggable rules and signals for risk scoring and blocking.
Horizontal autoscaling
Stateless workers and pods scale with load on Kubernetes.
High-level architecture
Microservices, event-driven processing, and message queues. Ledger consistency and horizontal autoscaling.
