Implemented the Transactional Outbox pattern with Kafka (Redpanda) to guarantee eventual consistency across distributed boundary contexts and checkout sagas. Standardized enterprise observability by integrating OpenTelemetry, Prometheus, Loki, and Grafana for comprehensive distributed trace and log correlation.
