I’m Marius Gjerd, a developer in Bergen, Norway, working at the bridge between IT and OT.
I started as an electrician. After getting my trade certificate I spent time on real industrial installations, the kind where a wiring mistake trips a breaker in a building, not just an error in a log. Then I transitioned into software, and for the past few years I’ve been building IoT solutions in the energy sector at Prelect, where the code I write talks to physical systems in the real world.
This autumn I’m starting a three-year degree in Industrial Automation at Fagskulen Vestland alongside my day job. PLCs, instrumentation, industrial networking, OT security. The formal industrial side of what I’ve been doing in practice.
What I write about
The gap between IT and OT is real and costly. Most developers have never touched a PLC. Most automation engineers have never debugged a cloud pipeline. I’ve done both, and I write about what I’ve learned at that intersection:
- What happens when the code you write has real-world consequences on real equipment
- How to trace a sensor reading from physical installation to cloud application, and where it lies to you along the way
- OT security from a developer’s perspective: what the threats actually look like, and what defences make sense
- What IT people get wrong about industrial systems, and what OT engineers get wrong about software
