Overview
The IroTeam multi-tenant IoT platform: 5,000+ greenhouse and access-control devices publish telemetry over MQTT into an ASP.NET Zero (ABP) backend, with tenant-isolated data feeding a Nuxt web app and customer portals — 2M+ events a day at 99.8% uptime.
I am the primary author of the backend (IroTeam.IOT solution) and the Nuxt front-end. The web app consumes live telemetry directly over MQTT-over-websockets alongside a GraphQL/REST API, with streaming charts (chart.js streaming plugin, amCharts) and PWA support for on-site operators.

Design patterns
Multi-tenancy (ABP)
Tenant isolation comes from the ABP layer — every device, zone, and reading is tenant-scoped at the data level.
MQTT pub/sub
Devices publish telemetry topics; the backend ingests them and the Nuxt app subscribes directly over MQTT-websockets for live charts.
Layered DDD (ASP.NET Zero)
Application / Core / EF Core layering with Web, Mobile, and All solution heads.
Offline-capable PWA
The operator web app installs as a PWA with Firebase push for alarms.
