Garu-City

A platform connecting the services of a smart city.

Modular platform for city councils: mobility, traffic, license plate recognition, fines, and urban services share a geospatial database and an operational map.

The problem

Municipal departments need to work with territorial data and field hardware while keeping each organization’s records strictly segregated.

The solution

Multi-tenant architecture with a Go API, PostgreSQL, and PostGIS. Telemetry is processed asynchronously with NATS JetStream and displayed on a React interface with MapLibre.

Core capabilities

Department-level modules and granular data permissions.
Geospatial map for urban services and traffic mobility.
Telemetry ingestion and distributed event processing.
Shared OpenAPI contract between Go API and frontend.

How it works

An interactive map coordinates field devices, municipal departments, and geospatial data.

Devices & Territory

The platform ingests field telemetry and works with GIS layers. Each municipal department has dedicated modules and permissions.

Services & Events

The Go backend coordinates municipal microservices. NATS JetStream enables reliable asynchronous telemetry processing, decoupling ingestion from analytics.

Geospatial Database

PostgreSQL and PostGIS persist system state and spatial geography. Multi-tenancy keeps records strictly segregated between organizations.

Operational Workspace

The UI unifies layers, field hardware, and city workflows on an interactive map. A shared OpenAPI specification connects frontend with backend services.
