Paper + 6 Video Walkthrough
This page contains the written paper and a six-part demo that shows how I approach architecture, intervention and governance in complex, real-world IT/OT environments.
Clarity • Stability • Real-world operation
Paper
A concise motivation and overview of the demo and its design choices.
Demo Paper (PDF)
This paper explains the intent behind the demo, the architectural assumptions, and what the videos illustrate in practice. It is written to be readable for both technical and non-technical stakeholders.
What you’ll get
A system-level view across data flows, networks and operational constraints — plus a pragmatic approach to intervention: diagnose, design, implement, stabilize and hand over.
The goal is not “a clever demo”, but a realistic blueprint for making complex environments governable.
Video Walkthrough (6 parts)
Short, focused videos. Each one covers a specific layer of the demo.
Overview & intent
What the demo is, why it exists, and how to read the rest of the series.
Architecture in practice
The structure behind the demo: layers, interfaces, and design choices that keep it maintainable.
Data flows & integration
How data moves from operations to systems that need it — reliably, predictably, and with clear ownership.
Networks & reliability
Practical approaches to segmentation, stability and troubleshooting when real-world constraints show up.
Security (built in)
Security decisions that support operations — without turning the environment into a brittle museum.
Governance & handover
How to keep systems governable over time: boundaries, ownership, runbooks and a clean operational handover.
