About Martijn
I build the layer between your systems and your insight.
Most technical environments are messier than they need to be. Sensors that log to nowhere, systems that can't talk to each other, data that exists but doesn't inform anything. I untangle that.
My work combines systems integration, IoT and data platforms, and end-to-end full stack development. I design and build the infrastructure that makes your data useful: from MQTT ingestion and time-series storage to interactive dashboards and web applications.
I work remotely and independently.
