I am a logistics expert, with a long history in simulation engineering, particularly in the field of container terminal (robotization).
Nowadays I am an independent simulation and IT consultant.
Besides that, I have always been a software developer, being one of the pioneers of Prestel emulators, a kind of predecessor of browsers. I have programmed in all kinds of languages ranging from Algol to Z80 assembler. Python is my favorite language for a couple of years.
I am the core developer of an open-source discrete event simulation and animation package, called salabim, which is used for a wide range of applications, ranging from warehouses, supply chains, ports, hospital logistics, and network optimization to material handling.
I am also the author of several open source packages including ycecream, MySimpleGUI and easy_property.
