The Internet Jigsaw

Internet and internet systems are like one big jigsaw. Every piece has to be on the right place. If just one piece isn't right than you won't get the result you hoped for.

E-commerce specialist

I am a E-commerce specialist and can help you with many questions about this fantastic way of selling you products or services. In the late '90 I started a web shop for selling white-goods over the Internet on the Dutch marked. I was the first one who did that and there was no software like Drupal of OS-Commerce. I had to invent it all by myself. It was a great time!.
The shop was very successful and some day a big company made me an offer that I couldn't refuse. So I sold my e-commerce business.

Now I use my knowledge to advice and help other e-commerce companies to get better, grow and make more profit. My strength is the combination between technique and commerce.

Fotografie

Fotografie is al sinds mijn jeugd een hobby. In de jaren '70 fotografeerde ik met een 2-hands grootbeeld spiegelreflex camera. Echt een oudje en ondanks zijn leeftijd een prima camera. Dat was in die tijd normaal dat je naast je camera ook een aparte, losse belichtingsmeter bij je had. Immers met de camera kon je niets ander dan scherpstellen, de sluitertijd en het diafragma instellen.
