Hi, I'm Valentijn, an enthusiastic developer from Arnhem.

I’ve loved making things for as long as I can remember, and wrote my first program when I was 8 years old, after I figured out our first 286 computer my parents brought home contained something called qbasic.

Fast forward to 2024 and with over 16+ years of experience as a full-stack developer, I’ve had the opportunity to work on a large range of interesting projects, from narrowcasting systems, advertising analytics, e-commerce to SaaS applications.

In my work, I like to focus on how the latest technical innovation can be used efficiently and value-oriented with the end user in mind. Within both my previous work as a freelancer and in my experience as a Sr. / Lead Developer, I have developed an affinity for working with various stakeholders to uncover and map requirements and solutions within more complex domains.
