This is the personal website of Koen de Jonge, my personal website.
Do get in touch with me via e-mail.

I was born in The Netherlands, Utrecht on February 28 in 1975.

I lived in the Appelstraat in Utrecht with my parents Tim de Jonge and Hanny de Jonge-Wubben from 1975 until 1977.

In 1977 we moved to Vlaardingen where my sister Lies was born.

In 1978 we moved to Roosendaal where in 1980 my brother Daan was born.

In Roosendaal I went to peuterspeelzaal de rakkertjes, later I went to the kleuterschool of the Josephschool, after that I went to the Fatimaschool then to the public school de Singel.

I learned to play the violin and later the viola in Roosendaal at the music school and I played in the music school string orchestra together with my sister who played Cello at that time.

My middelbare school was the Norbertuscollege also in Roosendaal. During that time I was the president of the student council for 4 years and I was the first student to do 9 different classes in the bovenbouw.

When I was 19 years old I went to Enschede to study Technische Bedrijfskunde (Industrial Engineering and Management) which I did for just one year.

In that first year at the University of Twente, in 1994, became a member of Data Net Drienerlo, a life changing event! I was introduced to the wonderful world of Electric Café, IRC, Multilink (Ringbreak!), Prograthons, WWCN, Loempies, and Linux (at first Slackware, later Debian, Redhat and Gentoo). I also became a member of Studenten Net Twente, where together with Auke van Slooten and Tjerk Vonck I created the Campustour, a virtual guide over the university campus.

In Enschede I was also part of the Musica Silvestra Orchestra, playing the Viola together with Job Oostveen, Ine Troelstra, Judith Dekkers and Joris Kemps and Erik van der Meulen.

The next study year I participated in the newly created study Bedrijfs Informatie Technologie (now Business and IT). I decided not to continue my studies at the university carrier. After working at several unschooled positions while looking for work in IT, I moved back with my parents by the end of 1996.

It was not for long before I found a job at the Rabobank in Etten-Leur who wanted to create an online back. I wrote a business plan for it, that I got to present at Rabobank Netherlands after which my project ended, the central department used my plan to create what later grow out to be what is now called Internetbankieren.

Soon after that in September 1996 I got at job at WL | Delft Hydraulics (now Deltares), at first via Randstad uitzendbureau, and in 1997 directly employed as IT Specialist.

In 1997 I bought a house in Delft: Harmenkokslaan number 13, which I completely renovated later. Shortly after that I became a member of the Koornbeurs.

I had a lot of fun at Delft Hydraulics with (among others) Paul Vlenterie, Raymond van der Plas, Leroy van Logchem, Bob de Groot and Arthur van Rooy doing Windows 95, Windows NT Server, Solaris, Sun Cluster, HP-UX, quite some Perl, SGI Irix and a lot of Linux.
