Supply Chain Visibility Stack (Go, Kafka, PostgreSQL, Grafana, React, Redis) overview

A real-time supply chain visibility platform built on Go microservices that ingest shipment events via Kafka, persist normalized tracking data in PostgreSQL, and cache hot-path lookups in Redis. Grafana dashboards expose KPIs like on-time delivery rate, dwell time, and exception counts to operations teams. A React frontend provides interactive map views and drill-down into individual shipment timelines. Designed for 3PL providers and enterprise shippers who need sub-minute latency on shipment status. The tradeoff is data quality — carrier integrations vary wildly in reliability and schema, requiring robust normalization and fallback logic.
