Observability & SRE for payment platforms — POC
The angle. A payment system tolerates neither silent failure nor a lost transaction. This POC connects my DevOps/SRE foundation to the demands of payments.
What I prototype
- Observability: metrics, traces, logs correlated around the transaction.
- SLO/SLA and alerting on critical paths (failures, latency, reconciliation).
- Resilience: retries, idempotency, controlled degradation on Kubernetes.
