I’m Pieter Leek
Industrial IT/OT Specialist
I bridge the gap between boardroom intent and factory-floor reality. I design Plant-to-Cloud data pipelines, troubleshoot high-impact failures, and harden industrial networks — with security built in, not bolted on.

Technical Services
Strategic architecture and hands-on intervention for complex industrial environments.
Plant-to-Cloud Pipelines
I design the Nexus between machine data and decision-making. Using MQTT and OPC UA, I build telemetry paths that scale to cloud and analytics — with data quality, lineage, and security as first-class requirements.
Industrial Networking
Stable OT starts with boring excellence: segmentation, routing, and predictable traffic. I build and troubleshoot industrial networks (often Linux-heavy at the edges) so the process stays stable and outages don’t cascade.
Troubleshooting
When production systems fail, I isolate root cause fast. I use Python, packet analysis, and protocol-level debugging to fix broken handshakes, overloaded gateways, and “it works in theory” integrations — without guesswork.
On-Site Commissioning
Hands-on on-site integration for machines and systems. I join your team worldwide to support FAT/SAT, cutovers, commissioning, and handover — where hardware, software, and humans meet reality.
About
I work at the intersection of IT/OT, data, networks, hardware and security. This is where industrial systems prove themselves in practice, or fail under pressure.
Complex challenges rarely fit within a single discipline. That is why I always take a broader view, from signals on the shop floor to complex international data pipelines.
My strength lies in connecting technical depth with real-world and human context. With over 20 years of experience, I connect hardware, software and the people who work with them.
I enjoy traveling and prefer working on-site, where systems truly come to life. My approach is calm and pragmatic: diagnosis, design, implementation, stabilization and handover.
