About

Let me introduce myself with a brief bio. My name is Kees van Zon, I am a retired engineer who worked at Philips from 1986 until my retirement in 2023. I started in the Consumer Electronics division and moved to Corporate Research after three years. My career, which spanned 37 years and two continents, had two phases of roughly equal length. My initial focus was on video processing for television applications, where I did system, board and chip design for several years before switching to software system design, architecture and implementation in 1992. In the second phase of my career I worked in healthcare informatics on the definition, design and implementation of software-based clinical decision support systems. While I did hands-on technical work throughout, I held, during most of my career, the position of technical project lead, with line management added in 2017. Prior to leaving the company I led a team of about forty scientists, many of them PhDs working in the field of Artificial Intelligence.

This website is an outlet for one of my hobbies: writing software apps. I have been writing software ever since I was introduced to programming in college in the late 1970s. Back then we used languages like ALGOL 60, Pascal and APL, along with a good dose of assembly language. My first home computer was an Acorn Atom that could be programmed in a version of BASIC.

At Philips I used Turbo Pascal in the mid 1980s, switching to C in the late 1980s. While I dabbled in C++, Java, JavaScript and PHP over the, years, C remained my main language until I encountered C# in 2005. That was love at first sight; while I have since also worked with Python at times, C# has been my go-to language ever since I was introduced to it.

I own a Mac computer but develop exclusively on Microsoft Windows® PCs, currently a Microsoft Surface Book 2, using Microsoft Visual Studio® as IDE. All apps that can be downloaded from this site were written in C# and target Windows 10 and higher. Web versions of some of the apps are in the works.
