Logistics / Fleet Management Stack (Go, PostGIS, Redis, Kafka, React, Grafana) overview

A fleet management and logistics optimization platform built on Go microservices that ingest real-time GPS telemetry, store geospatial position data in PostgreSQL with PostGIS extensions, and cache active vehicle states in Redis for sub-second dashboard updates. Kafka handles event streaming for route deviation alerts and delivery confirmation workflows. A React frontend with map components provides dispatchers with live fleet visualization. Grafana monitors fleet health KPIs like utilization rate and idle time. Targeted at logistics companies, delivery services, and field-service organizations managing 100+ vehicles. The tradeoff is telemetry volume — high-frequency GPS pings generate substantial write load, requiring careful partitioning and retention policies on the geospatial data layer.
