I'm Cristian, class of '87. I work in IT by trade, but a tinkerer by nature: I take things apart to understand them, and then I tell you why they work.
When I study a complex subject, the first thing I look for is a simple explanation. If I can build a clear mental image, the rest follows on its own.
First a metaphor a child would understand: a picture to keep in mind.
Then the engineering deep dive: architectures, algorithms, protocols, data structures, internals.

Tools change. Principles remain.
From sensors to MES, from PLCs to industrial cybersecurity.
