I find it utterly difficult to come up with quality photos of work related to me that won't bore the viewer. Instead, I'll show you random pictures I took during times that I didn't work.

I’m available for freelance work that takes no more than 16 hours per week. And it has to be located in or very near Rotterdam.

With ongoing other freelance projects, a family with 3 kids and plenty of hobbies, I have an interest in using my time efficiently. For me, that means not spending an hour or more on the road each day. That means that I usually don’t take any freelance jobs outside of Rotterdam.

Thank you for not bothering me about permanent jobs, work in Amsterdam or JAVA development. I’m not interested.

I do take great interest in building data-driven web applications that deliver as much business value as possible in changing environments.

Roles I take on are Full Stack Developer/Engineer, Web/API Developer, Javascript Expert, SQL Server Specialist, Marketing Technologist and Product Owner.
