About
Hi, I’m Arjen
I'm an experienced web developer with almost 20 years in ecommerce. I build webshops that are reliable, fast, and well-architected — and I care about finding the best solution, not just the easiest one.
Beyond development, I mentor other developers, help shape team processes, and occasionally speak at conferences. I hold Magento 2 certifications as Professional Developer, Frontend Developer, and Solution Specialist.
