Phase 5 Capstone Deliverable
The Phase 1 app now uses production-grade data infrastructure:
- Kafka for async messaging between Go and Python
- PostgreSQL with HA, backups, and zero-downtime migrations
- Redis with Sentinel for caching and rate limiting
- All stateful services monitored with Prometheus + Grafana dashboards
