About
I'm Jason Krijgsman, a data product and infrastructure specialist based in Rotterdam, currently working at GGD Rotterdam-Rijnmond.
I help organisations turn a data question into a working product. That starts with the question, definitions and requirements, followed by the data infrastructure, analysis or model needed to answer it.
I have worked in aviation, freight, construction, film and home entertainment supply chains, and public health. The subject changes, but the practical work is similar: learn how the process and data fit together, then build something people can use.

The route through it
My work has moved through very different settings, but the same question keeps returning: how can you see enough of a system to make a better decision?
- Aviation and freight. I started with the movement of aircraft, cargo and people, where delays and capacity emerge from many connected decisions.
- Construction. On an Amsterdam building site, simulation exposed a safety problem that was invisible in an approved traffic plan.
- Airports. Capacity studies and a digital twin of Mexico's largest airport connected operations, data and predictive modelling.
- Home entertainment. At Disney, the system became an EMEA supply chain crossing SQL, SAP/BW, forecasting and reporting.
- Public health. At GGD Rotterdam-Rijnmond, I work on infrastructure and products for regional monitoring.
- Independent systems. Bliep brings the same curiosity to firmware, electronics, radio networks and hardware.
Education and qualifications
I completed an MSc in Business with Business Analytics at Northumbria University with Distinction. I also hold a BSc in Aviation from Amsterdam University of Applied Sciences, a vocational qualification in aviation logistics from STC Rotterdam and Certified Data Management Professional (CDMP) certification through DAMA.
Dutch is my first language, and I work fluently in English (IELTS 8.5). I also buildBliep, a mesh radio device. For this project I work on firmware in C, electronics and hardware certification.
What I'm working on now
At the GGD, I work on infrastructure for regional public health monitoring. Outside that role I develop small studies for the public data lab and continue to work on Bliep.
