• Situation: Fragmented rule-based OT stacks; legacy machines exposed to scanning and lateral movement.
• Task: Build a unified, multiprotocol edge gateway for secure telemetry and cloud/SCADA interoperability.
• Action: ARM/x86 hardware, Linux + Docker containers, Node-RED/Python pipelines; Zero Trust overlays for passwordless access, cloaking, and policy-based microsegments.
• Result: <1s machine-to-cloud flow; 99.9% uptime; 30% downtime reduction via 24×7 telemetry and predictive analytics.
• Tools/Tech: Azure IoT Hub/Edge, AWS IoT Core/Greengrass, GCP Pub/Sub/BigQuery/Vertex AI, MQTT Broker, OPC-UA, RS-485/RS-232, Node-RED, Python, C++, Docker/Podman.
