UNIX System AdministratorI worked nearly three years at Vuurwerk Internet. My responsibilities included setting up a FreeBSD dedicated hosting platform, performing physical installation of servers, building servers, maintenance, scripting/programming, and serving as a third-line escalation point. It was a privilege to work with so many skilled engineers and developers at Vuurwerk.
Developer / System Administrator / ShareholderI was part of a start up that listened to the name Discard BV and was a shareholder. I worked as a programmer and system administrator for Discard, writing software that mined fraud sensitive information from malicious (public and underground) sources such as stolen credit card numbers. We provided a service with which you could be alerted whenever your credit card was being traded in underground communities. Our initiative got some media attention (CNN, and a major US business magazines), yet there was little animo for such a service at the time. Alas :)

EntrepeneurMy company HJ Hosting gained national notoriety when newspapers, radio stations and television stations made mention of my initiative. It started out as a free e-mail service promoting freedom of speech. After the media attention I decided that I would offer hosting services at a low price and gained more than 3,000 customers overnight and it went viral. It was a one man show, from customer support to system administration. Exhausting but fulfilling.
