Why this blog exists

Hi, I’m Marius Gjerd, a developer based in Bergen, Norway, working at the crossroads of code and physical infrastructure.

I started out as an electrician. Then I learned to write software, and for the past few years I’ve been building IoT solutions in the energy sector.

This autumn I’m starting a three-year degree in Industrial Automation alongside my day job. It covers PLCs, instrumentation, industrial networks, and OT security. That’s a deliberate move. The bridge between IT and OT, between the cloud-connected world of developers and the physical world of industrial control systems, is somewhere I find genuinely interesting, and a place where very few people are comfortable on both sides.

This blog is where I’ll write about what I learn along the way.

What to expect

Expect posts on:

• The strange and useful corners where IT and OT meet
• Industrial cybersecurity from a developer’s perspective
• Hands-on experiments with PLCs, sensors, and home labs
• Lessons from building IoT at scale in energy
• Whatever else I find worth sharing as I work my way through the degree

I’ll write when I have something to say, not on a schedule. Some posts will be technical deep-dives; others will be shorter reflections. All of it will be in my own words, and the code behind the projects will be open source on my GitHub.

If any of this is interesting to you, stick around.
