Summary
🤩
Rockstar🎓
Top SchoolRandy Armstrong is a seasoned Chief Software Architect with three decades of systems and full-stack engineering experience and two decades focused on industrial automation, cloud integration, and IoT. He has led specification and SDK development for OPC UA, chaired security working groups, and architected solutions that connect factory devices to enterprise and cloud platforms including Azure and AWS. Equally comfortable in embedded C/C++, .NET, Java microservices, and modern web stacks (React/Node), he designs secure, distributed systems spanning OPC, AMQP/MQTT, and satellite-linked remote monitoring. His work blends standards leadership (authoring OPC UA spec parts) with hands-on product delivery—examples include OPC UA-enabled HMI/SCADA integrations, an iOS OPC UA client, and an SDK for industrial developers. Based in Richmond, BC, he brings rare depth in both international specification development and pragmatic engineering for harsh, resource-constrained industrial environments.
