The plant, the data, and everything between.

I’ve spent fifteen-plus years inside industrial control systems — SCADA rooms, PLC panels, BTU meters, the telemetry that keeps a city’s chilled water moving. Most of what I learned there never made it out of the control room.

This site is where it comes out. I write for the engineer who has to keep the plant running on Monday, not for the conference stage — which mostly means being specific about what breaks, honest about what the trade actually costs, and willing to say when the fashionable answer is the wrong one.

The beat

SCADA software — the platforms the plant actually runs on, and what changes when they stop behaving like SCADA
MQTT and the unified namespace — the pattern underneath the hype, and where it earns its keep
OPC and open architectures — interoperability as it works in the field, not on the datasheet
OT security — the exposure that matters, told apart from the protocol panic
The open-source IIoT stack — Node-RED, Grafana, InfluxDB, Postgres — loved by every OT engineer, run with confidence by few plants

Writing and Lab

Writing is the argument side — architecture, economics, and the industry reading itself wrong. Lab is the evidence side: real gateways, real brokers, real clusters, built on hardware I own and reported with the numbers I measured — including the runs that contradicted what I expected going in.

The through-line across both: the plant, the data, and everything between.
