I'm Pieter Leek
Technical Systems Architect | Connecting Technology, People & Decision-Making | Built for Problems Without a Manual
I get excited about technical and organisational challenges that others would rather avoid. Often it involves systems that don't talk to each other, stalled integrations, unclear ownership, or technical debt that nobody fully oversees anymore. I step in, map the situation quickly, and find the real problem behind the symptoms.

Where I Help
Technical architecture, diagnosis and recovery in environments where systems, people and decisions no longer align.
Architecture Between Boardroom and Floor
Technical problems rarely live in one place. They often sit between systems, teams, priorities and decisions. I connect the technical reality with the organisational context, so decisions are based on how the environment actually works. I create overview, identify the real bottlenecks and translate complex technical situations into a direction that teams and decision-makers can act on.
Legacy, Middleware & Connectors
When machines, applications, databases and cloud platforms do not speak the same language, I design and build the layer in between: protocol translators, edge data services, API wrappers, message pipelines and practical middleware that makes information flow again.
Sensor-to-Cloud Architecture
From field sensors and edge devices to dashboards, databases and cloud services. I design practical architectures where data can be measured, transported, stored and used for research, monitoring and decision support.
Complex System Diagnosis
Something keeps breaking and nobody can pin down why — or worse, everyone has a theory and the fix never holds. I read the system as a whole: network, software, integration, data, process and the way people are actually using it. Usually the cause sits across two of those, which is why nobody found it. I trace it, explain it and help make sure it does not come back.
Technical Recovery & Go-Live Support
Go-live coming up, a project drifting, or a technical environment that has become too unclear to steer? I step in quickly, create overview, separate symptoms from causes and help move the project back to a state where delivery is possible again.

About
I work where technology, people and decision-making meet — especially when the situation no longer fits a standard manual.
The bigger picture. Instead of just looking at symptoms, I look for the root of the problem. I prefer working from the main lines rather than drowning in micromanagement. That creates the clarity and overview needed to make decisions and get things done.
A broad toolkit. My background is deliberately broad: software development, infrastructure, IoT, education, team leadership, governance and process improvement. I've built environments from hardware sensor to cloud dashboard and connected operational systems to business processes. I use whatever is needed at that moment to solve the actual problem.
Technology and the human side. A system only works when the people around it do too. I switch just as easily between software stacks and the people on the shop floor or in the boardroom. Not by playing a role, but through genuine interest in how the environment actually works.
Short, intense, and results-driven. My strength lies in project-based engagements, usually up to 12 months. I come in to solve a problem, build what's needed, secure the quality, and hand it back over cleanly.
Based in the Netherlands. Available for project-based assignments, remote-first where possible and on-site when the situation requires it.
Reference Work
Amerta One — Solar-Powered Field Module for Rice Fields
Amerta One is a current Qman reference project: a small solar-powered field module that measures local salinity stress risk in rice fields, gives farmers a simple LED status indication and sends measurement data to Tirta Cloud for research, calibration and future advisory services.
The project combines the kind of work I like most: field hardware, ESP32/LoRa, power design, cloud data, practical research and a clear human purpose. It is a sensor-to-cloud system built for real environments, not just a dashboard demo.
The first prototypes are being developed for field testing, with the long-term goal of placing multiple modules in Central Java to support salinity monitoring and farmer advice.
The architecture reflects my broader way of working: connecting hardware, software, data, people and decision-making into one understandable system.
